EXECUTIVE SUMMARY

The Ujh Multipurpose Project is located in district Kathua of Jammu and Kashmir which is on River Ujh one of the tributary of River Ravi. The River Ujh is joined by other four tributaries Sutarkhad, Dunarikhad, Bhini and Talyan at a place called Panchtirthi, a name which is derived from the confluence of these five streams. The proposed project is a multipurpose project with intended benefits of hydropower, irrigation and drinking water. The Jammu and Kashmir State Power Development Corporation has proposed project as186 MW (3x 62) + 26 MW (1x24 + 1x2) for hydropower and Irrigation potential of 16743 ha for agriculture land. Theproposed dam site is in the village Barbari about 1.6 km downstream of Panchtirthi. The proposed powerhouse site is approximately 9.5 km down stream of dam site near village Deoli. A Barrage has been proposed 1.5 km d/s of Power house. Two canals, Right Main Canal (RMC) and Left Main Canal (LMC) will be emanating from barrage along both the banks of the River. From each of the canals ten cusec water has been earmarked for drinking water for the district Kathua of J&K.

The RMC will provide irrigation in tehsil Kathua, Hiranagar and Samba district while, the LMC will provide irrigation in district Kathua. The Canal Command Area (CCA) of RMC is 5595ha and CCA of LMC is 3053 ha. In addition to that, the RMC will irrigate an additional area of 8095 ha in Kharif season from Samba to Vijaypur in the command area of existing Ravi and Tawi canals.

Installed capacity of Ujh Multipurpose Project has been proposed as 186 MW. In addition to that a dam toe powerhouse comprising of two units, one of 2 MW and another of 24 MW has been proposed to harness the hydro-electric potential of the water meant for mandatory environmental releases. The unit of 2 MW will run through the environmental releases in lean period as well as in monsoon period while the unit of 24 MW will run through the releases in the monsoon months of July, August and September. The cost of the Project is estimated to Rs 363073.00 lakhs at April 2013 price level.

Hydrology

Water availability studies for the project have been carried out by Central Water Commission based on inflow series of 23 hydrological years (June to May) for the period 1984-85 to 2006-07 after deducting environmental flows to be released directly into the River (recommended to be utilized for power potential studies). Ujh River drains a catchment area of 854 km2 at the dam site.

Based on the hydrological studies, annual run-off during the study period varies from a maximum of 2362 MCM (year 1984-85) to a minimum of 412 MCM (year 1989-90) with the average run-off being 1041 MCM. The average inflows in the River during monsoon months from June to October constitute about 76% of the total average annual run-off. The average inflows in the River during lean months from Nov. to Feb. constitute just about 12% of the total average annual run-off. The minimum monthly flow in the flow series have been observed as 0.97 cumec in Feb, 2001 and the maximum flow of 335.54 cumec in August, 1984. TheProbable maximum Flood value of 11400 cumec has been recommended by the CWC for the planning of Ujh Multi purpose project.

Sedimentation Assessment

The sediment data observation at Ujh dam site was done during August, 2010 to January, 2011. No sediment observation data is available on Ujh River prior to August, 2010. The average annual sedimentation transport rate is worked out as 0.33 mm/year, whereas it is considered as1mm/year including 20% bed load in this study.

The Reservoir Sedimentation problem has been classified as insignificant as per Bureau of Indian Standards (BIS: 12182). As such the sediment inflow into the reservoir has been worked out considering the variable trap efficiency using the Brune’s Median Curve for normal ponded reservoirs. The New Zero Elevation (NEZ) corresponding to 50 years & 100 years have been computed which works out to 514.63 m and 523.15 m respectively against the original bed level of 503 m.

Power Evacuation Assessment

As, there is no upstream or downstream hydro power project in the vicinity of Ujh Multipurpose Project and therefore the evacuation of this generation project only is required to be planned. It is proposed that the generated power will be evacuated through a 220KVDC line from generation switchyard to 220/132kV Hiranagar substation of PDD,J&K. The length of this 220 KV line will be 15 kms (approx).

Environmental Impact

The construction as well as operation activities of the project have certain impacts on the ecosystem, which are temporary and could last only till the construction activities. The expected areas of impact due to construction of the project are land environment, water environment, air and noise environment, terrestrial flora, wildlife, aquatic environment and socio-economic environment.

The nearest protected area is the Jasrota wildlife sanctuary. Jasrota Wildlife Sanctuary lies on the Bank of River Ujh near Jasrota Village which has 25.75 Sq. km area. The proposed right main canal (RMC) of UJH Multipurpose project is passing about 1km north of the sanctuary. Canal alignment of RMC has been fixed to avoid the sanctuary and finally the underground alignment is fixed approximately 1 km away from the sanctuary.

Total area under submergence below Maximum Water Level (MWL) is 41 sq km ,out of which 16.94 sq km is private agriculture land, 10.59 sq km is state revenue land, 5.17 sq km is barren land,5 .88 sq km is shamlat land and remaining 2.42 sq km is forest land. 4.70 sq.kmForest land is falling under submergence along the periphery of the reservoir area.Environmental Impact Assessment will be carried out in view of EIA notification, 2006, guidelines of Central Electricity Authority and Ministry of Ground Water Resources. An Environmental Management Plan (EMP) will be prepared to minimize the adverse impacts on the environment. The most reliable way to ensure the implementation of EMP is to integrate the management measures in the overall project planning, designing, construction and operation phases.

Social and Infrastructure Impacts

Property Survey of Submergence area of Ujh Multipurpose Project was conducted in association with J&K State Revenue Department in 12 villages. In all these 12 villages, total number of families falling in submergence area below elevation 615.5m (MWL) are 2235 out of which 689 families belongs to Scheduled Caste community and 70 families belong to Scheduled Tribe.

Sixty four temples are falling under submergence below MWL but majority of them are small temples of local deities. The famous local temple of Lord Shiva at Panchtirthi is also falling under submergence below MWL. In addition to temples, 2235 houses, 4 mosques, 23 government schools, 4 tube wells, one private school, 1 lift irrigation, 17 government buildings and 13 small structures of cultural importance are also falling under submergence area below MWL.

Rehabilitation and Resettlement plan for Ujh Multipurpose Project will be prepared based on National Rehabilitation and Resettlement Policy, 2007.The salient features of the project are given below.

Chapter 1: Introduction of the Project

1.0 Background Information

The Jammu and Kashmir State Power Development Corporation has proposed Ujh Multipurpose Project located in district Kathua of Jammu and Kashmir. The proposed project is on the River Ujh, which is one of the main tributary of River Ravi (Figure 1.1). The River Ujh is joined by other four tributaries Suterkhad, Dunarikhad, Bhini and Talyan at a place called Panchtirthi. The confluence of these five streams derives the name of the location as Panchtirthi. The Ujh and Bhini are perennial streams and the remaining three streams flow during rainy season only. The location of dam site is between 75º29’ 16”E and 32º33’ 48”N. The dam site of the project is located in tehsil Billawar of the district Kathua which is about 1.6 km downstream of Panchtirthi. The location of Power house is between 75º27’ 58.4’’ E and 32º32’ 38’’N which is located approximately 9.5 km downstream of dam site near a village called Deoli. A Barrage has been proposed d/s of Powerhouse which also lies between 75º27’ 31.1’’ E and 32º 32’ 1.22’’ N. Two main canals, Right Main Canal (RMC) and Left Main Canal (LMC) will be emanating from barrage along both the banks of the River. The RMC will pass through tehsil Kathua, Hiranagar and Samba district, while LMC will pass through district Kathua. GCA and CCA of LMC are 5684 ha and 3053 ha respectively. GCA and CCA of RMC are 14364 ha and 5595 ha. In addition to that in kharif season, RMC will irrigate additional area of 8095 ha of existing Ravi Tawi canal from samba to vijaypur. Installed capacity of Ujh Multipurpose Project has been proposed as 186 MW which would enable peaking operation of the powerhouse for about 4 hrs with a load factor of about 16.7%. Further, the annual energy benefit from the project in the 90% dependable year would work out to be 263.68Million Unit (MU). The firm power from the project has been estimated as 31.09 MW. Three unit of Francis turbine with the unit size of 62 MW have been proposed for the power house. In addition to that a dam toe powerhouse comprising of two units, one of 2 MW and another of 24 MW has been proposed to harness the hydro-electric potential of the water meant for mandatory environmental releases. The unit of 2 MW will run through the environmental releases in lean period as well as in monsoon period while the unit of 24 MW will run through the releases in the monsoon months of July, August and September. The annual energy benefits from this dam toe power house will be 31.7 MU. This will make the total annual energy benefits from the project to the 335.48 MU. 10cusec water has been earmarked through each main canal i.e. RMC and LMC of the project for drinking water for the district of Kathua in J&K.

1.1 Brief description of nature of project

The Ujh project is a multipurpose (Hydropower, Irrigation and Drinking) River valley scheme andis first of its kind in Jammu and Kashmir State. The proposed project is on the River Ujh, which is one of the main tributary of River Ravi. Installed capacity of Ujh Multipurpose Project has been proposed as 186 MW+26 MW which is Category A project and comes under 1 (C)as per the EIA notification, 2006. .Total area under submergence below MWL is 41 sq km ,out of which 16.94 sq km is private

Project Location

agriculture land, 10.59 sq km is state revenue land, 5.17 sq km is barren land,5 .88 sq km is shamlat land and remaining 2.42 sq km is forest land. Forest land is falling under submergence along the periphery of the reservoir area.

Jasrota wildlife sanctuary lies on the Bank of River Ujh near Jasrota Village and has 25.75 Sq. km area. The Proposed right main canal (RMC) of UJH Multipurpose project is passing about 1km north of the sanctuary which is shown in Figure 2.2. A lot of exercise was done to fix the canal alignment of RMC to avoid the sanctuary and finally the underground alignment is fixed approximately 1 km away from the sanctuary. Total 12 villages come in the submergence area. In all these 12 villages, total number of families falling in submergence area below elevation 615.5m (MWL) are 2235 out of which 689 families belongs to scheduled caste community and 70 families belong to scheduled tribe.

Sixty four temples are falling under submergence below MWL but majority of them are small temples of local deities. The famous local temple of Lord Shiva at Panchtirthi is also falling under submergence below MWL. In addition to temples, 2235 houses, 4 mosques, 23 government schools, 4 tube wells, one private school, 1 lift irrigation, 17 government buildingsand 13 small structures of cultural importance are also falling under submergence area below MWL. Rehabilitation and Resettlement plan for Ujh Multipurpose Project will be prepared based on National Rehabilitation and Resettlement Policy, 2007.

1.2 Need for the project& Importance

The State of J&K is perpetually energy deficient and has to rely on power purchase fromNorthern Grid to meet its requirement particularly in winters, when its own generation recedes and demand peaks.

The estimated hydropower potential of the State is 20,000 MW, out of which about 16480 MW have been identified. Out of the identified potential, only 2457.96 MW i.e. 15% (of identifiedpotential) has been exploited sofar. Due to resource constraints, exploitation of the potential economic rejuvenator like hydro power has been very steady. The demand and availability scenario (Energy in MU) of J&K is given in Table 1 and the demand and availability scenario(Peak Power-MW) of J&K is given in Table 2..

The figure shows that from 2007-08 to 2012-13 the actual demand has increased from14037

MU to 17842.69 MU respectively. The power short fall has increased at an alarming rate.Recognizing the urgency and need of development of this sector, there is an urgent need ofhydropower development and hence the implementation of this project becomes veryimportant. The power of Ujh MPP will increase the power availability of northern grid and J&K state will be benefited by this additional power.

Irrigation Water Demand

The maximum irrigation water requirement is estimated for last 10 daily of month of May and is 40.97 MCM. Accounting for demand for rush irrigation, maximum irrigation water requirement is 45.07 MCM. Gross-Irrigation and drinking water requirement has been tabulated in the crop water requirement table annexed as Annexure-III. RMC and LMC will provide the irrigation facilities to Kandi belt of Jammu province which is under developed in agriculture as there is no irrigation facility in this belt and farmers depends only on monsoon.

Domestic Water Demand

A provision of 10 cusec of water has been made through each of the canal for drinking purpose. The Kathua district and particularly the Kandi belt is facing problem of water shortage. In summer season there is a huge gap between demand and supply of the drinking water and people of district especially of Kandi belt suffers a lot. Villagers very often resort to the ponds for drinking water, which is not hygienic. When the ponds dry up in the summer, villagers have to trek long distances to fetch drinking water. The water from proposed Ujh project will sort out the problem of drinking water up to a large extent. The water of proposed Ujh Multipurpose Project may also be used by industries which are growing fast in district Kathua.

Flood control

Ujh River causes heavy floods in monsoon in Kathua district causing loss of precious lives, structures, crops etc. Floods of River Ujh causes loss of crores of rupees to state exchequer. The high flood discharges, which are mostly flashy, devastate size able hectares of cultivable area downstream of the national high way crossing. The land on both the banks of the River issubjected to severe erosion and submergence. The proposed storage dam will slightly modify the flood duration and peak and with controlled releases the flood damage can be minimized if not entirely eliminated and crores of rupees of state exchequer will be saved.

Indirect Benefits

TourismThe artificial lake with a water spread of about 41 sq. km shall become one of the biggest recreational spots in Jammu province. It shall provide enough facilities for boating, water skiing and other aquatic sports. The tourists after visiting this lake are also likely to visit other tourist spots near to this project like Mansar Lake, Surinsar Lake and famous pilgrimage places in the area like Sukrala Devi Ji temple, Balasundri Devi Ji temple thus increasing the tourist potential of the region

Development of fisheriesThe reservoir, having a water spread of 41sq.km will provide an ideal opportunity for developing Pisciculture in the State. The reservoir can be stocked with improved seed in keeping with local climatic condition. About 500tonnes of the fish is expected to be obtained annually and after fulfilling local demands will be exported to other states.

Development of industriesThis project will help in development of industries of Kathua and Samba districts because sizeable portion of power produce shall be available for development of industries in the region. In addition to power, water will also be supplied to the industries. During construction of project, construction materials like cement, steel, aggregates and other material will be required at large scale and the large demand will increase the development of industries in the region.

Infrastructure improvementInfrastructure like roads, bridges, buildings etc. will be built at a large scale at the construction stage of the project which will benefit the local people also.

1.3 Employment Generation

Besides power, the proposed project has both direct and indirect benefits. Provision of drinking water, irrigation, electricity, flood controls are among the direct benefits. In addition tothese major benefits, there will be indirect benefit for tourism, development of fisheries,industries, infrastructure improvement in the form of road sand buildings. Besides, the projectwill have a potential for employment generation which will help in the socio-economicdevelopment of the people of the region.

2.3 Detail of Alternatives Sites

Dam Site

The detailed investigation for dam and power plant were taken up by the erstwhile CW&PC (now CWC) in the year 1960 and that of irrigation canal system by the State Government. The investigation on the present Barbari site was started by the CW&PC in the year 1961, and the work of detailed contouring of the area was entrusted to the Survey of India. In November, 1961 the site was inspected by the CW&PC, GSI and J&K State Government. During the inspection, it was suggested to explore an alternative site for the dam near Challa village, 2 kmbelow Barbari Site. Accordingly, preliminary surveys and investigations were conducted on the alternative site by the GSI and CW&PC. The alternative site was not found to be attractive by the GSI. The merits and demerits of the alternative sites were examined by CW&PC and the State Govt. It was found that the original Barbari site had topographical and geological advantage over the Challa dam site; hence the original dam site at Barbari was finally selected.

Location of Barrage

Studies were undertaken for the alternative locations of barrage. Earlier, State Government had proposed the barrage site about500 m downstream of the tail race channel outfall. Later, itwas shifted to the present location which is 1.5 Km downstream of Tail Race Channel (TRC) asthe earlier location was very close to the power house and the level difference between TRCout fall and the barrage location was very low and there was a possibility of impact of backwater on the power house.

Alternative Alignment of the Canals

The earlier decided alignment of RMC of Ujh MPP was passing through the Jasrota WildlifeSanctuary. As, it was not possible to construct the canal or to lay under ground pipes throughthe wildlife sanctuary hence, various alternatives were explored and contemplated upon by the experts from the GSI and designers of CWC to circumvent the sanctuary. After detailedtopographic survey and geological mapping of the area the alignment has been finalized. It will be passing about one km away from the sanctuary. This alternative alignment will be underground and passing through the forest area between Bhakta khad and Tarnah Khad. Also fromthe geological view point this alternative has been found most suitable.

2.4 Size or magnitude of operation

Ujh Multipurpose Project has been proposed as 186 MW which is Category A project and comes under 1 (C)as per the EIA notification, 2006. Total area under submergence below MWL is 41 sq km ,out of which 16.94 sq km is private agriculture land, 10.59 sq km is state revenue land, 5.17 sq km is barren land,5 .88 sq km is shamlat land and remaining 2.42 sq km is forest land. Forest land is falling under submergence along the periphery of the reservoir area.

2.5 Project description with process details

The Ujh MPP is envisaged with 3x62 MW generating units and it is proposed to set up the generation at 220 KV level. As, there is no upstream or downstream hydro power project in the vicinity of Ujh Multipurpose Project and therefore the evacuation of this generation project only

is required to be planned. It is proposed that the generated power will be evacuated through a 220 KVDC line from generation switchyard to 220/132 kV Hiranagar substation of PDD, J&K. The length of this 220 KV line will be 15 kms (approx). Considering 10% additional generation over design capacity of 186 MW, the quantum of power to be evacuated will be of the order of 200 MW. In view of this proposed 220 Dc line is to be constructed with zebra conductor and design for 85 degree centigrade maximum temperature. It has been discussed and decided by CEA and PDD J&K to terminate this line bays can be accommodated by extending 220 kv switchyard for which land is available. The Power from 220 kv generation switchyard will be taken through 220 kv XLPE cables (6+1 spare) and GIS to air inter phase will be provided for taking off 220 kv overhead D/C line to hiranagar. The outdoor 220 kv line equipments viz. LAS, CVTs and wave traps shall be provided for both 200 kv lines.

2.6 Raw material required along with estimated quantity, likely sources, marketing area of final products, Mode of transport of raw material and finished product.

Cement and steel will be supplied by the department from its store located at the project siteand oil and lubricants are available at Kathua and it is connected to the UMPP site through theNational Highway-1A. Both fine and coarse aggregates are to be processed from the rivershoals located near the power house site and rock material required for construction are fromthe quarry area near the dam site(Coarse aggregate from river shoal is 4 lakh cum and coarse aggregate from quarries is 16 lakh cum)

2.7 Resource optimization/recycling and reuse envisaged in the project, if any should be given

Machinery used in the project will be shifted to other projects for use.

2.8 Availability of water its source, Energy/ Power requirement and source Input Data for Power Potential Studies:

Selection of FRL & MDDL

As per the Pre-feasibility assessment, 2004, the FRL had been selected as 614m. However, in the present study, possibility of raising the FRL beyond 614m was also explored. Based on the field surveys conducted by CWC, the submergence details &the population affected for alternative FRL scenarios of 614m, 620m, 630m & 640m, are summarized below:

FRL Population Affected (Nos.) Area submerged (km2)

(M) Houses People Total Agricultural Land614 1067 6293 38.55 24.77620 1275 7542 45.45 30.44630 2214 12786 55.18 37.50640 2643 15117 64.91 46.61

It was observed that large scale submergence is involved for the alternative FRL beyond 614 M. It is further seen from the studies discussed in succeeding paras that there would be hardly any spills from the reservoir for alternative FRL of 614m and, as such, additional energy generation would be negligible for FRLs beyond 614m. As such, the alternative FRL beyond 614 M have not been considered.

For selection of MDDL, it is observed that New Zero Elevation for the project after 50 years and 100 years of sedimentation works out as 514.63m & 523.15m respectively. As such, the minimum alternative MDDL has been considered as 564 m from sedimentation as well as turbine head variation considerations.

For selection of the optimum FRL and MDDL for the project, Reservoir simulation studies have been carried out in CEA for alternative FRL scenarios ranging from 608 m to 614 m in a step of 2 m considering MDDLs varying from 564 m to 594 m in a step of 10 m. Results of the simulation studies indicating firm power, power output and annual energy benefits from the project are given at Annexure-VI (A) to (P) and results of these studies are summarized below:

It is observed that the flow data is available for a period of 23 years. As such, 5 failures would be permissible for irrigation based on 75% dependability. However, no. of irrigation failures are more than 5 for the FRL alternatives of 608 m and 610 m, as such these alternatives have been ignored and further analysis has been carried out for FRL of 612 m and 614 m only.

In case of FRL-614 m, the irrigation failures exceed the permissible no. of failures for MDDL above 584 m while in case of FRL-612 m; the irrigation failures exceed the permissible no. of failures for MDDL above 574 m. As such, the permissible alternative scenarios of FRLs and MDDLs would be as under:

FRL (m) MDDL (m)614 564

For selection of the FRL and the MDDL, a detailed Cost-benefit analysis has been carried out for the above three alternatives taking into consideration the tentative cost of dam at different FRLs as furnished by CWC and considering the cost/MW of E&M Works as Rs. 1.5 Crs. Results of the analysis are summarized below:

90% Dep. Year

Firm Power & Installed Capacity

With the FRL and the MDDL for the project as 614 m and 564m respectively, the firm power from the project has been estimated as 31.09 MW. Installed capacity for the project has been proposed as 186 MW which would enable peaking operation of the power house for about 4 hrs. with a load factor of about 16.7%. Further, the annual energy benefits from the project in the 90% dep. year (1990-91) would work out to be 263.68 MU. Design energy benefits from the project (with 95% machine availability in 90% dependable year) have also been assessed as 263.68MU

With the FRL and the MDDL as 614m and 564m respectively, the net head acting on the turbines would vary from about 100m to 150m with weighted average net head as about 138m. Accordingly, a francis turbine would be suitable for the above head range.

The transport limitations to the project site in terms of the largest package have been indicated as 3.75 m (W) X 4.8 m (H) with the weight of heaviest equipment that could be transported as 68 T. As such, there is unlikely to be any major constraint in transportation of heavy and large size equipment to the project site. Accordingly, three units with the unit size of 62 MW have been proposed for the project.

Corresponding to the weighted average net head of 138 m, the unit discharge would be of the order of 51 cumec.

Conclusion

Finalized features of Ujh Multipurpose Project would be as under:

3.7 Climate

The areas falling in Kathua district experiences wide range of climate from sub-tropical to temperate area and even alpine in higher regions of Bani and Lohai-Malhar blocks. Because of altitudinal variation, there is vast difference between the temperature of two plain tehsils of Kathua and Hiranagar with those of Hilly Tehsils of Basohli and Billawar. The summer temperature rises as high as 48 degree Celsius in the plains and winter temperature in the upper hilly areas touches sub-zero. Most of the higher areas in the Basohli and Billawar Tehsils experiences snowfalls for most part of the year. The District experiences rainfall during winter and early summer primarily from western disturbances and monsoon rains from second week of July onwards. The hilly areas receive more rains than the plains. The annual rainfall in the district is approx. 1672 mm.

3.8 Social Infrastructure available

The social infrastructures are very well found within the district which was listed in Table 3.3. Property survey of Submergence area of Ujh Multipurpose Project was conducted in association with J&K State Revenue Department in 12 villages. Sixty four temples are falling under submergence below MWL but majority of them are small temples of local deities. The famous local temple of Lord Shiva at Panchtirthi is also falling under submergence below MWL. In addition to temples, 2235 houses, 4 mosques, 23 government schools, 4 tube wells, one private school, 1 lift irrigation, 17 government buildings and 13 small structures of cultural importance are also falling under submergence area below MWL. Details of different type of structuresunder submergence below EL 615.5 m (MWL) is shown in Table 3.3.

Chapter 4: Planning Brief

4.1 Planning Concept

The Ujh Multipurpose Project is located in district Kathua of Jammu and Kashmir. This project is on river Ujh which is one of the main tributary of river Ravi. The river Ujh is joined by other four tributaries Suterkhad, Dunarikhad, Bhini and Talyan at a place called Panchtirthi, the name derived from the confluence of these five streams. The proposed dam site is in the village Barbari about 1.6 km downstream of Panchtirthi. The Powerhouse site is approximately 9.5 km downstream of dam site near a village called Deoli. A Barrage has been proposed 1.5 km d/s of Powerhouse which also lies in tehsil and district Kathua. Two canals, Right Main Canal (RMC) and Left Main Canal (LMC) will be emanating from barrage along both the banks of the river. The RMC will provide irrigation in tehsil Kathua, Hiranagar and Samba district while, the LMC will provide irrigation in district Kathua. Installed capacity of Ujh Multipurpose Project has been proposed as 186 MW. In addition to this, a dam toe powerhouse comprising of two units, one of 2 MW and another of 24 MW has been proposed to harness the hydro-electric potential of the water meant for mandatory environmental releases. The unit of 2 MW will run through the environmental releases in lean period as well as in monsoon period while the unit of 24 MW will run through the releases in the monsoon months of July, August and September.

Hydrological investigations are essential for proper planning and design of hydro electric Projects. For planning the Project features, available Hydro-Meteorological data was collectedfrom JKPDC and Gauge, Discharge, Rainfall and Meteorological sites were established for the collection of data.

The gauge and discharge observations of River Ujh were started by JKPDC in the year 1989. The long term data of River Ujh is available at Damsite, Barbari and Power housesite, Jakhol.The data availability at these two sites is as follows.

Gauge and Discharge observation sites on River UJH were established by CWC at Ujh Damsite and Ujh power house on 9.10.2009 and 01.10.2010 respectively. Daily discharges alongwith three time gauge observations (i.e.8.00 hrs, 12.00 hrs and16.00 hrs) are been made atthese sites during the non-monsoon season (November–April). However during monsoonmonths daily discharges and hourly gauges are being observed. The cross sections of theRiver Ujh at discharge sites are taken during the lean months for calculating the segmentareas.

Water Availability Studies

Before utilizing the discharge data of River Ujh for developing the long term flow series fordetermining the water availability at the dam site, the following consistency checks were appliedto as certain the accuracy and reliability of the data available:

Consistency Checks

i) Mass curve: It can be seen from the mass curve of the observed series that the data for theyear 1990-92 appears to be in consistent. Mass curve shows prominent kinkin the observeddata for the period1990-91 and1991-92.

ii) Run-off factors: Annual run off factors observed at Ujh Dams how that run off actor isabnormally low during these years.

Year Run off factor1990-91 0.211991-92 0.24

An average run off actor of 0.85 has been observed for the period 1985-2007 and shown in Figure 4.1.

Figure 4.1: Mass Curve of Ujh Barrage

iii) Ratios of 50% and 90% dependable flow: The ratio of 50% and 90% dependable flow hasbeen worked out as 2.22 and the corresponding ratio for the X 50 to X 90 has been found as1.31. There is a wide variation in the two ratios. In view of the above, it is considered appropriateto modify the observed flow data for the year 1990-91 and the year 1991-92. The same hasbeen done with the help of working out the annual yield based on the average rain fall run off factor of 0.85. The annual yield obtained so has been further distribution into thirty six 10-daily values by using the ratio of observed average 10-daily flow for a particular 10-daily period to thesum of observed average annual flow. The observed and modified flows are given in Table 4.1.

Design Flood studies

The Ujh dam is a major dam and therefore, the design flood for the Ujh dam shall beProbable Maximum Flood.

Estimation of Design Flood

The design flood studies for the Project have been carried out using both hydro-meteorological and statistical approaches.

a) Unit Hydrograph Approach

The CWC had carried out design flood studies in 1962 and derived unit hydrograph for theUjh dam project using observed in flow data at Ujh dam site. However, the same could not be validated for want of primary data used in the derivation of UG. In the absence ofconcurrent observed rainfall and discharge data availability, the unit hydrograph has alsobeen derived using synthetic approach based on CWC Sub Zone-7 Report both for Ujh aswell as Bhini River separately. The derived UGs are given in Table 4.2.

i) Design Storm, Temporal Distribution, Loss rate and base flow

The 1-day Probable Maximum Precipitation (PMP) for Ujh Dam project has been taken from the PMP atlas of IITM (2008) as 44.9 cm. Using clock hour correction factor of 1.15, the 24 hrPMP works out to be 51.6 cm. Temporal distribution of 24-hr PMP has been taken from CWC Sub Zone-7 Report which was also compared with time distribution observed at Dalhousieobservatory situated near to the project catchment. Both the distributions are almost similar. The loss rate has been adopted as 0.25 cm/hr. The base flow for the rain fed has been taken

@ 0.05m3/s/km2 as given in the Sub Zone-7Reports.

ii) Probable Maximum Flood

Probable maximum flood at the Ujh dam using SUG and observed UG (1962) with1-day PMPvalue of 44.9 cm have been computed as 11400 cumec and 10060 cumec respectively.

b) Flood Frequency Analysis

Observed annual flood peak series is available from year 1989 to year 2008 at the Ujh dam site. The annual maximum series has been checked for randomness and out liers and theseries is found to be random and trend free however the observed peak value of 5536 cumecin the year 1995 is found to be out lier with marginal difference. However, the same has beenincluded in the flood frequency analysis. Based on standard error, the Gumble Type I wasfound to best fitting distribution which gives 10000 years return period flood as 11132 cumec. Commonly used distribution functions were fitted to the data series and the result of the floodfrequency analysis is as given in Table 4.3.

Approach to Dam site

Approach to Damsite of the project up to Mandli, Gura and Thara Kalyalis through Dhar Roadwhich is in good condition. The machinery and material can be transported through this road from Jammu, Pathankot and Kathua Railway station to the link point of dam site i.e. Mandli,Dramni and Gura. The existing approach roads from Mandli, Dramni and Guracan be usedduring construction stages only as these approach roads falls in the submergence area of the reservoir.

Two alternative alignments of proposed roads to the dam site have been identified and basedupon the techno economic consideration one of them can be selected and adopted.

The first proposed road is above FRL and can be used even after construction of dam. This road will start from Kandharno at Dhar road which is about 3 km from Challan and 4 km from Nagrota. This road will pass from Galak, Rajwalta, Agli dhar, Rean villages and the length ofthis road from Kandharno to dam site is approximately 20 Km from Kandharno to Galak, 6 kmssingle lane road. The approximate distance of this road from Rajwalta to Dam site is 14 kmswhich will have to be constructed a fresh.

Second proposed road to dam site is from Power House site. This road will start from Power

House site and will pass through right bank of river Ujh through Mota village to reach dam site.The length of this road is approximately 11 kms.

These two alternatives alignments of the proposed roads are to be studied carefully fromdifferent perspectives but as of now the second alternative i.e. road from Power House toDamsite appears to be more suitable because of following reasons.

This road will also cover surge shaft, HRT, a dits of HRT and muck disposal areas throughsmall connecting roads.

Construction of separate permanent colony for dam site will not be not required and thecolony near power houses it can be utilized for dam site also.

Forest area involved in construction of this road is lesser than forest area involved in thecase of first alternative.

Approach to Power house site

Nearest railway station to power house site is Kathua which is about 34 kms from power house site and nearest airport to power house station is Jammu which is about 83 km from Power house site. Power house site of Ujh MP Project can be approached through nationalhighway upto Rajbagh. From Rajbagh to Jakhol, there is single lane 13 km long metalled road.From Jakhol to power house the 4 km distance is to be covered on foot. Before reaching power house site river Ujh is required to be crossed at two places.

Barrage site of Ujh MP Project is approximately 1.5 kmsD/s of power house site and theapproach is same as that of the power house site. The proposed main canals (RMC and LMC)are also approachable from National Highway at many intermediate points.

The Power House site is approachable upto Rajbagh through the National Highway. FromRajbagh to Jakhol, the 13 kms long existing single lane metalled road is proposed to be upgraded to double lane metalled lane. It is also proposed to construct a 5 kms double lane road from Jakhol to Power house site via Deoli village where some of residential quarters andtemporary structures are proposed to be built. Heavy machineries and electro mechanicalequipments are required to be transported to the power house through this road. Hence, theroad from Rajbagh to Power house is proposed to be widened as double lane with larger curves so that the load upto hundred tones and eight axle vehicles can be transported.

Approach to other Project Components:

Connecting roads to the portal of in take structure on right bank, inlet and outlet portal ofdiversion tunnels on left bank, spillway on the left saddle and u/s and d/s coffer dams havebeen planned through the main road to the dam site.

Connecting roads are also planned to in take, HRT, adits of HRT, muck disposal area, surgeshaft, pressure shaft etc and these roads will be connected to the proposed main roadbetween power house site to dam site. The approximate length of these connecting roads is about 10 kms.

Connecting roads to some points of canals are also proposed and approximate length of theseroads is approximately 5 km. These roads for both right main canal and left main canal will jointhe various existing link roads originating from Delhi Jammu national highway.

6.6 Drinking water Management (Source & Supply of water)

Quantity of water supply for drinking and construction purpose would be met from the river Ujh itself. It is proposed to install a tube well of sufficient capacity near the river Ujh at d/s of power house to supply the water to the residential and office complex. A filtration plant is also proposed near lift station at d/s of the barrage site.

6.7 Sewerage System

Both, residential and non-residential buildings have been proposed on the project site. A STP/Septic Tank has been proposed for sewage treatment.

6.8 Solid waste Management

Both, residential and non-residential buildings have been proposed on the project site. Any municipal solid waste generated in the project complex / project colony / labour colony, shall be managed and handled in accordance with MSW Rule, 2000.

6.9 Power Requirement& Supply/ Source

It is assessed that on average 25 MW of power would be required during construction stage and tabulated in Table 5.3

Table5.3: Requirement of Power for ConstructionS.No Area Maximum Demand (MW)

1 Batching Plant 12 Refrigeration System 83 Aggregate Process Plant 44 Tunnels 45 Conveyor at Dam Site 45 Colony / Workshop Area 16 Total (in MW) 227 Considering a diversity factor 0.9

The requirement of Construction Power is assessed (in MW)

25

It is estimated that an overall peaking energy of about 25 MW will be required during the construction for which necessary DG sets with 100% back up have been proposed. Necessary transmission lines are also proposed from Rajbagh to Colony site, Power house site, HRT and Dam site.

Chapter 6: Rehabilitation & Resettlement Plan

Property Survey of Submergence area of Ujh Multipurpose Project was conducted in association with J&K State Revenue Department. On request of the Central Water Commission,Tehsildar, Billawar deputed a team of officials of revenue department to conduct propertysurvey of reservoir area of Ujh Multipurpose Project with field Engineers of Central WaterCommission. The Reservoir area of Ujh Multipurpose Project falls under Tehsil Billawar of district Kathua. This area comes under four Niabat namely Buddu, Phinter, Gura and Ramkotand each Niabatis headed by NaibTehsildar. Property survey of the reservoir area undersubmergence below the elevation 615.5 m (MWL) was conducted. Property survey of areabetween 615.5 m to 620 m was also conducted for future requirement if any.

Below MWL (EL615.5m), two revenue villages Dungara, Dharalta are falling fully insubmergence area and ten revenue villages namely Bhaddu, Beril, Durang, Pallan, Barota, Aglidhar, Dharamkot, Dher, Malti, Rampur are falling partially under submergence area. In allthese 12 villages, total number of families falling in submergence area below elevation 615.5 m (MWL) are 2235 out of which 689 families belongs to scheduled caste community and 70families belong to scheduled tribe. Total population falling under submergence below MWL in allthe villages is 11495 out of which 3867 are scheduled caste and 427 are schedule dtribe. TheDungara village, near to Panchtirthi has maximum number of families under submergence as compared to other villages. Nargari and Kishanpur villages are part of Dungar are venuevillage. The reservoir area extends from the dam site upto 7.5 km along the main Ujh River, 9.5km along the Bhini River in the eastern side and 10.5 km along the Talyan Khad in the westernside. Sutar and Dhunari Khad are the other important catchments of the reservoir area.

Rehabilitation & Resettlement Plan (R/RP) for Ujh Multipurpose Project will be prepared based on National Rehabilitation and Resettlement Policy, 2007.

Affected people will be assisted in regaining their economic status in the initial stages in such a way that they can sustain on their own and do not have to depend on the project authorities for long. The project authorities will slowly phase-out their assistance and leave the affected people to depend on their own economic activities and social lifestyle.

Chapter 8: Recommendations

The state of J&K is having water resources in abundance which is the backbone of the economy. The Indus, Chenab, Jhelum and Ravi are the four major River basins of the State. All these rivers have their source in the glaciers and so are perennial. The water bodies of the J&KState have enormous economic potential in the shape of hydro power generation, irrigation and tourism. The estimated hydro power potential of the State is 20,000 MW, out of which about 16480 MW have been identified. Out of the identified potential, only 2457.96 MW i.e. 15 % (of identified potential) has been exploited so far, consisting of 760.46 MW in State Sector from 21 power projects, 1680 MW from four power projects under Central Sector i.e. {690 MW SalalHydel Electric Project, 480 MW Uri-I Hydel Electric Project, Dulhasti 390 MW and 120 MW Sewa-II} and 17.5 MW from two private sector projects. The installed capacity of 760.46 MW from state sector projects includes the 450 MW of Baghlihar Phase–I constructed at a cost of 5827 Crore by the J&K State Power Development Corporation which was commissioned on 9-10-2008.

Due to resource constraints, exploitation of the potential economic rejuvenator like hydro power has been very steady. Besides, due to the constraints imposed by the provisions of Indus Water Treaty between India and Pakistan preventing water storage of the water of Jhelum, Chenab and Sindh Rivers these projects have been constructed as run of the Rivers schemes. The State is, therefore, perpetually energy deficient and has to rely on power purchase from Northern Grid to meet its requirement particularly in winters, when its own generation recedesand demand peaks.

Ujh River is a tributary of Ravi River and joins River Ravi at Nainkot in Pakistan. According to Indus water treaty India can fully utilize the water of eastern Rivers and its tributaries. Hence, after the completion of this project the water which is going unutilized to Pakistan can be properly utilized. The State of J&K is perpetually energy deficient and hastorely on powerpurchase from Northern Grid to meet its requirement particularly in winters, when its owngeneration recedes and demand peaks.

Ujh Multi Purpose Project UMP) in District Kathua of J&K is one of the National Projects. The technical sanction to the project estimate was accorded by CWC on 4.03.2009. CWC started project investigation from April 2009. Subsequently, the detailed estimate for the investigation and preparation of DPR was formulated amounting to Rs 1723 lakhs. The technical sanction to the estimate amounting to Rs 1723 lakhs was accorded by the Chief Engineer, IBO, CWC, Chandigarh on 4.03.2009.The detailed Project report has been prepared.

The project will address local and national priorities by being a multipurpose project which has components of power generation and transmission, drinking water supply and irrigation facilities in a region (especially the Kandi belt) which is witnessing power shortage, inadequate potable water supply and irrigation facilities. The UMP will provide additional benefits like flood control,pisciculture, tourism etc.
