SUCCESS STORIES OF 2016

IWM Vision

Among the major clients of IWM; BBA, BIWTA, BMDA, BWDB, CPA, CWASA, DPHE, DWASA, LGED, RHD, WARPO etc. stand big to seek IWM services. These agencies play significant role regarding taking large projects which involve development of country and the people. With IWM’s services of modelling and survey our clients can ensure the optimum performance and outcome of these projects and thus save resources of the country in terms of millions of dollars. The vision of IWM is aligned with the Perspective Plan of Bangladesh, Vision 2021.

Coast, Port andEstuary Management

Bangladesh Government has a strategic plan to become a middle-income country by 2021. Energy supply thus increases rapidly in order to sustain the country’s economic growth. The study focuses on selection of location of LNG terminal site, establishing formation level and protection measures considering cyclonic storm surge & wave action and coastal erosion. Analysis shows that Formation Level of 50 years return period is 10mMSL considering 1:7 side slope. On the basis of existing topog-raphy/land level, area and required Formation Level, the volume of sand needed to fill the area is about 21.43 million m3 for Site- 2 (450 acre) and 51.54 million m3 for Site-1 (700 acre). Considering the filling height and volume, costing and navigational depth Site-2 is better compared to Site-1. Considering sediment charac-teristics, distance, costing of dredging and transport of

d r e d g i n g material to t h e p r o p o s e d site, the chars at and around the Moheshkhali C h a n n e l Estuary is the best suitable s e d i m e n t source for dredging and

filling the low-lying area. A suitable cutter suction dredger may be useful for dredging the selected chars and a hopper barge can be used for carrying the dredged materi-al from the dredging location into the filling site. The effect of the Project on the national economy is indicated by the

Economic Internal Rate of Return (EIRR). The benefits of the project interventions have been identified and quanti-fied as far as possible for economic analysis. The EIRR is 21.52%, which is above 12%, i.e. the opportunity cost of capital investment.

The study area covers three coastal districts namely Bagerhat, Borguna and Patuakhali located at the eastern

side of the Sundarbans. Locations for mangrove afforestation were selected considering mainly, the storm surge v u l n e ra b i l i t y a n d adequate foreshore length & width of coastal polders and tidal characteristics. Four locations have been selected under this research project to assess the effects of mangrove afforestation in reducing the vulnerability of coastal polders.There are various kinds of

mangrove species are available in the selected sites. In this study, mangrove species are short listed based on

local people experience and multi-criteria analysis, the criteria are salinity level, tidal characteristics, local availability and economic value for the selected study sites. In this study, Keora and Baen are selected based on the multi-criteria analysis.

In this research work, upgraded and updated hydrodynamic model (water flow model) for Bay of Bengal is used to assess the effects of mangrove afforestation effects. From 1960 to 2015, cyclone SIDR was most devastating for the south-west region of Bangladesh. Therefore, cyclone model is developed for the cyclone Sidr (2007). The developed cyclone model is added into the hydrodynamic for developing the storm surge model. In the hydrodynamic model mangrove afforestation is developed in terms of manning roughness.

Storm Surge level considering different scenarios

Mangrove tree creates resistance to the flow. The flow of water through the mangrove forest is obstructed by the matrix of roots/trunks of the mangrove trees, which creates bed resistance. This bed resistance is represented by equivalent Manning number. For calculation of the equivalent Manning number of mangrove tree, both the trunks and the roots of Keora (Sonneratia apetala) and Baen (Avicennia officinalis) species have been considered. Manning roughness is calculated based on water depth for the root system and trunk system individual.

Eq-1 is used for calculating the manning roughness for the

root system and Eq-2 is used for calculating the manning

roughness both for root and trunk system of mangrove afforestation system.

In this study, 50m, 100m width of Keora and Baen afforestation in the selected site-1 and 2 and 1000m and 2000m width of Keora and Baen trees with are selected in the selected site-3 for assessing the mangrove

afforestation effects. 5m by 5m and 7.5m by 7.5m spacing

of Keora trees and 4m by 4m and 6m by 6m spacing of

Baen trees are selected for afforestation density variation.

50cm sea level rise and 8% wind speed is increased to

develop the climate change impact for assessing the

effects of mangrove afforestation during the period of cyclone.

Mangroves can reduce storm surge water levels by slowing the flow of water and reducing surface waves (McIvor et al., 2012). It is observed that 50m/100m width of afforestation by Baen trees reduces surge level by 3cm to 5cm and Keora trees can reduces the surge height by 4cm to 6cm in the selected site-1 and site-2. In the selected site-3, the surge level reduction is found by 11cm to 28cm for Baen and 11cm to 29cm for Keora trees for 1000/2000m width of mangrove afforestation. It indicates that the surge attenuation of different widths of mangroves is non-linear (Zhang et al., 2012). Therefore mangroves can potentially play a role in coastal defense and disaster risk reduction (McIvor et al., 2012).

Different options are applied to assess the water flow during cyclone. Different mangrove afforestation width and afforestation density, and different species are considered under this research for calculating the flow velocity during cyclone. With 50m/100m afforestation of Baen trees with 4m by 4m spacing, the flow velocity

reduces from 64% to 72% and for 6m by 6m spacing of Baen trees it is reduced by 54%. Afforestation of Keora trees shows more positive result than the afforestation of Baen trees. Flow velocity reduces by 79% and 87% for 1000m and 2000m afforestation of Baen trees with 4m by 4m spacing and 80% and 88% for 1000m and 2000m afforestation for Keora tress with 5m by 5m spacing in the selected

site-3 respectively. The reduction of flow velocity by 61% and 74% is also observed for 2000m width of Baen and Keora trees respectively for different density. Therefore, variation of mangrove species and densities shows the significant effects on the flow speed during cyclone.

Stakeholders consultation workshop on 28 November 2016 at BWDB, Dhaka, Bangladesh

General assembly, 07-10 March 2017 at Athens, Greece

General assembly, 26-29 January 2016 at Bologna, Italy

European Union (EU) funded EartH2Observe is integrating available earth observations from different satellite missions, in-situ datasets from various sources, and state-of-art models to construct a consistent and robust Global Water Resources Reanalysis (WRR) dataset of sufficient length. This project consists of a number of case-studies to evaluate the applicability of the Earth Observation (EO) data and the Water Resources Reanalysis (WRR) data for water management at national or river basin levels. The case study for Brahmaputra basin is being conducted in Bangladesh by the Institute of Water Modelling (IWM) focusing on the assessment of flow. Water management in Bangladesh is more and more problematic due to the growing demands by agriculture, the urban and industrial sectors, fishery, inland navigation and salinity control. Due to future development plan of trans-boundary courtiers the water availability is threatened, especially in the downstream of the catchment. The focus of this case study is to determine the availability of water resources, now and in the future in the Brahmaputra river basin utilizing Earth Observation (EO) products and IPCC climate change scenario projections and subsequent re-analysis of these datasets.

The Brahmaputra is one of the world's largest rivers, with a drainage area of 556,365 sq. km. originating from the great glacier mass of Chema-Yung-Dung in the Kailas range of southern Tibet; it traverses China, India and Bangladesh

before emptying into the Bay of Bengal. Being a unique river, it drains such diverse environments as the cold dry plateau of Tibet, the rain-drenched Himalayan slopes, and the landlocked alluvial plains of Assam and the vast deltaic lowlands of Bangladesh. The Brahmaputra Basin model has been developed using DHI software package by computing runoff using Rainfall-Runoff Model (NAM) and routing of flow in channels using MIKE Basin. Several EO products such as TRMM, GsMAP, CMORPH and reanalysis products such as WFDEI and MSWEP are compared with observed rainfall data of this basin. Developed Brahmaputra basin model has been simulated with those rainfall products. Computed runoff using different EO products and reanalysis rainfall products has been compared at Bahadurabad station with rated discharge. Performance of the basin model has been evaluated by computing Pearson Correlation Coefficient (r) and Nash–Sutcliffe model efficiency coefficient (E). Monthly average flows generated by several global hydrological models has been compared with rated discharge at Bahadurabad to identify best suitable data set and performance of global hydrological models for the Brahmaputra basin. Two different workshop was organized relevant to stakeholder consultation on 08 June 2014 and 28 November 2016. IWM study team has been attended several meeting and conference in abroad regarding the study to present the progress of the work, plan of future work and overall evaluation of the study.

management of water resources in an integrated manner. In this regards, a contract agreement between DBHWD and IWM was signed on November 10, 2016. The study area covers Habiganj, Maulavibazar, Sylhet, Kishoreganj, Netrokona and Sunamganj districts. The major activities to accomplish the study objectives are hydrogeological investigations, assessment of water resources using mathematical modelling and development of an Interactive Information System (IIS). Groundwater elevation contour map for dry season of 2015 reveals that ground-water is flowing mainly towards the central part (haor area) of the study area from neighboring area.

National Water Balance Management (NAWABS) for Sungai Muda, Kedah, Malaysia

The Sungai Muda Basin in Malaysia is part of an area more popularly known as the Rice Bowl of Malaysia has an area of 4,150 km2. Increasing water demand mainly for agriculture and potable water supply has caused water stress in the area which becomes more pronounced especially during dry seasons. Conflicts in water allocation are more apparent between these different water use sectors and users from different states relying on the same water source. The issue becomes more complex as the management of dams and river infrastructures are developed and managed by several different agencies from the state and federal levels.As an effort to resolve the water issues, which are antici-pated to get more acute, Jabatan Pengairandan Saliran (JPS), Malaysia has initiated the development of tools which will help stakeholders make informed decisions.

Detailed Feasibility Study with ESIA for Restoration of Water Resources around Baral River Basin

Bangladesh Water Development Board (BWDB) has

undertaken a study named “Detailed Feasibility Study with ESIA for Restoration of Water Resources around Baral River Basin”. The Baral River is one of the distributaries of the Ganges River which originates from Ganges river at Charghat of Rajshahi district and flows through Rajshahi, Natore, Pabna & Sirajganj districts. A regulator having 3-vents was constructed on Baral river in 1984 at Charghat. Then another two structures were also constructed, one having 5-vent on Nandakuja branch and the other one having 1-vent on mora Baral at Atgoria of Bagatipara Upazila.

Major problems relating to water resources management in the study area are as follows : During dry season, the water level at Ganges

becomes lower than the bed level of Baral near the off-take.

Off-take channel of Baral, most of the length of mora-Baral and some portion of associated rivers have been silted up

Lot of encroachments have been occurred through-out the length of Baral and its distributaries and tributaries and hence the flow has been constricted

Number of bridges, culverts and other structures have been constructed by different organizations among which most of them do not have sufficient opening with higher invert level to accommodate requisite conveyance of the river system

Flow at the downstream of Atghoria regulator has been diminished due to conservation of water at the upstream by constructing two regulators for agriculture, fisheries and other uses.

To provide technical support by applying modern techniques of mathematical modelling BWDB engaged IWM to conduct this study on 4th April 2016. The main objective of this Study is to provide technical support by applying modern technique for Detailed Feasibility Study with ESIA for Restoration of Water Resources around Baral River Basin with a view to ensure flow of Baral river and identification of potential areas suitable for surface water based irrigation scheme. The study will address a sustainable solution for reviving the Mara Baral and other rivers in the project based on model results and all necessary initiative will be taken up to strengthen the projects and impart adequate flow with drainage. The study will also address the requirements of any structure in addition to the existing ones.

River Engineering

River Engineering Division (REN) endeavors in the field of river engineering and management, and uses state-of-the-art mathematical modelling technology in the following disciplines :

• Fluvial hydraulics and river morphology• Erosion management (river training and bank

protection works)• River dredging management• Offtake management• Sediment management for hydraulic structures

(dam, barrage, regulator, etc.)• Road/bridge infrastructure management• Hot water dispersion and cooling water intake

in rivers for Power Plants

The division inherits its strength in the field of hydro-morphological mathematical modelling of large, meandering and braided rivers, for over two decades, through persistent involvement with the very complex river system of Bangladesh including three major rivers: the Ganges-Padma, the Brahmaputra-Jamuna and the Meghna.

REN Division offers technical assistance to the relevant professionals of several organizations, with the aid of state-of-the-art mathematical modelling, to harness most of the beneficial uses of rivers ensuring minimum adverse impacts.

REN with its expertise and experience was involved in many projects during 2016, notable ones are :• Hydro-morphological Mathematical Modelling Study

for Re-excavation of the Bhairab River flowing over Meherpur and Chuadanga Districts

• Feasibility Study for Dredging along the Gumti River for Smooth Drainage and Ensuring Dry Season Irrigation Facilities at Daudkandi and Adjacent Areas in Comilla District Using Mathematical Modelling including Environmental and Social Impact Assessment (ESIA)

• Hydraulic and Morphological Study of the Ghorautra River around Mithamain Area for establishing Cantonment

• Study for the Protection of Guide Bund at the Barisal End of the Bir Shrestho Captain Mohiuddin Jahangir Bridge (Doarika Bridge) on the Sugandha River.

REN continued its involvement, as of previous few years, during 2016 in the following projects, which are considered nationally important ones. These are :

• Gorai River Restoration Project Phase-II• Monitoring of Hydraulic & Morphological Conditions

of the Jamuna River for the Safety of the River Training Works of Bangabandhu Bridge during the Period 2013 to 2017

Besides the projects mentioned above, REN carried out hydrological and morphological studies, using mathematical models, for a few important bridge projects (of Roads and Highways Department-RHD, and Local Government Engineering Department-LGED).

A set of highly skilled professionals are engaged in accom-plishing sophisticated numerical modelling at REN; their expertise and knowledge are being updated and upgraded through on-the-job training, and attending seminars and workshops at home and abroad. Moreover, basic and applied research programs are conducted in order to maintain a high level of technical competence. One such research project titled Assessment of Suitability of Sediment Predictor of the Major Rivers of Bangladesh was taken up in 2016, Phase-I of which has already been completed.

The Bhairab River originates from the right bank of the Ganges River, about 30km upstream from India- Bangladesh border, at Nasirpur (Jalangi) of Murshidabad district of West Bengal, India. The river enters into

Bangladesh near Kathuli in Meherpur district, then flows along east-south direction – over Meherpur Sadar and Mujib Nagar upazillas of Meherpur district, and Damurhuda and Jibon Nagar upazillas of Chuadanga district, then finally meets the Mathabhanga River near Subalpur. From Kathuli to Subalpur, the length of the Bhairab River is about 86km.

In the past, the Bhairab was a high-flowing perennial river – one of the main distributaries of the Ganges River. The river used to serve for navigation, irrigation and drainage purposes. About a decade or so, a regulator was constructed by the Indian Government at her own jurisdiction over the Bhairab River – at about 5km upstream from the India-Bangladesh border. Owing to controlling the river flow by the regulator, the Bhairab started to lose its flow inside Bangladesh. The trans-boundary river suffers severely from scarcity of water for irrigation and farming in the dry season for quite some time. With the prolonged adverse situation, the socio-economic and environmental conditions have deteriorated gradually.

As a result, it had been the demand of local people for quite some time to make suitable arrangement so that the river water would be available for dry season irrigation and domestic purposes. Addressing a large rally in Mujib Nagar in 2011, the honorable Prime Minister of Government of Bangladesh promised to the local people for re-excavation of the Bhairab River.

Re-excavation of the Bhairab, for a length of 29km – from Kathuli to Rashikpur – started on 23 April 2015. However, local people demanded for re-excavation of the rest 57km

of the Bhairab River. In fact, for optimum utilization of the Bhairab River water, it is necessary to re-excavate the whole 86km of the river – from Kathuli to Subalpur.

Development of Bhairab River would be technically and socially complex intervention that needs comprehensive analysis of the hydro-morphological scenarios of the river system. IWM was contracted by Bangladesh Water Development Board (BWDB) on the 7th of August 2016 to carry out hydro-morphological mathematical modelling for the Bhairab River.

The main objective of the mathematical modelling study is to assess the feasibility of the envisaged re-excavation of 57km reach of the Bhairab River (from Rashikpur to Subalpur) from technical point of view, and find out feasible options for water resources development and management including flood control and drainage improvement as well as improvement of navigability in the study area.

The model results will be utilized in finalizing the hydraulic design variables such as velocity, discharge, water depths, water levels, etc. on the basis of the different flow events. These design variables will be of great help for safe and economic design of the re-excavated section of the river and other hydraulic structures (if required) to assess its feasibility, and to assess water retention as well as irrigation potential.

The Gumti River, originating from Dumboor, northeastern hilly region of Tripura state of India, follows meandering course of about 150 km and enters Bangladesh near Katak Bazar. Travelling about 90km within Bangladesh through Burichang, Debidwar, Muradnagar and Comilla Sadar Upazillas, it finally falls into the Meghna at Shapta, Daudkandi upazilla under Comilla District. Flash floods

having strong current are common phenomena of this hilly river that occurs at regular intervals. Because of its origin in the hilly region, it carries huge sediment during the monsoon, resulting significant silting up of the river bed at various locations, especially at the outfall of Gumti to Meghna that is hampering the smooth and timely drainage. Scarcity of water for irrigation and farming in the dry season is the prevailing problem of the Gumti dependent area in Bangladesh. Some Irrigation projects located adjacent to the Gumti River are facing scarcity of irrigation water in the dry season, viz. Sundalpur and Sonaichari irrigation projects.

Although, presently the Gumti appears to be under control with respect to flood damages because of implementation of a number of BWDB projects, earlier designed crest level of the flood control embankments is threatened to be inadequate to hold flood water and save valuable lands and property.

In consequence of these adverse situations, the socio- economic and environmental conditions of the Gumti

dependent area have deteriorated gradually. To address and thereby to resolve the issues concerned, Bangladesh Water Development Board (BWDB) decided to conduct a feasibility study, which would assess the base condition and formulate effective solutions for the existing problems.

IWM has been entrusted to carry out the Feasibility Study, and a Contract Agreement was signed on 4 April 2016 to conduct a study titled Feasibility Study for Dredging along the Gumti River for Smooth Drainage and Ensuring Dry Season Irrigation Facilities at Daudkandi and Adjacent Areas in Comilla District Using mathematical Modelling including Environmental and Social Impact Assessment (ESIA).

The main objectives of the study are to assess the prevailing hydro-morphological

feature (flooding/drainage, sedimentation/erosion, etc.) of the Gumti River with special reference to its outfall, to recommend sustainable measure to resuscitate the outfall, and to assess the impact of such resuscitation on agriculture, fisheries, environment and overall socio- economic condition of the study area, and make sure the availability of irrigation water at Sundalpur and Sonaichari Irrigation Projects.

Survey and DataManagement

Survey and Data Division (SDT) of IWM conducts hydro-graphic and topographic surveys including collection of water quality and sediment data to support scientifically based management of river erosion, flood and irrigation, water supply and sewerage system. SDT also supports planning and implementation of infrastructure in the communication sector, urban development, industry and energy sectors.

The specific areas of SDT activates are: hydro-morpho-logical survey including water quality and sediment sampling and analysis in the rivers and estuaries, flood plain topography and engineering survey.

SDT uses the latest survey equipments like Robotic Total Station, RTK-GPS, DGPS, Echosounder, Turbidity Sensor and Acoustic Doppler Current Profiler (ADCP) along with the specialised computer software and facilities to conduct the surveys. Addition of new equipment has increased the capacity of conducting Offshore measure-ment like longterm current & wave monitoring in the sea and Measurement of Turbidity and relating with Suspended Sediment Concentration. The surveyed data is promptly processed and analysed in the field and thus maintains a near-online quality control procedure. In the office the data is further verified by the senior professionals before transmitting it to the users and archived in the database for future applications. In addition to collecting data to support modelling activates, SDT also supports different Government Agencies in implementation of dredging activates in the major rivers.

A set of motivated staff comprising highly skilled professionals and field surveyors are engaged for the jobs. The knowledge and skills of the staff are continuously updated and upgraded through on-the-job training, discussions, seminars and workshops at home and abroad.

Payra Port Authority (PPA) has signed MOU with Jan De Nul Group (JDN) of Belgium for carrying out capital and long term maintenance dredging to develop the Payra Deep-Sea Port. Jan De Nul investigated the morphological and hydrological condition of the Rabnabad Channel and proposed Navigation Route from the Port Area to Outer bar. As a part of their investigation, Institute of Water Modelling (IWM) conducted a series of hydrometric measurement campaigns at Rabnabad channel of Kalapara Upazilla under Patuakhali district. The campaigns were conducted during August 19 to September 04, 2016; during October 10 to 26, 2016 and

during December 12 to 18, 2016. Among many other components, continuous current and wave measurements were carried out by using Teledyne RD Instrument’s Sentinel V ADCP. The equipment has the capability of measuring current and wave simultaneously and was mounted on a special frame manufactured by Mooring System Inc., as shown in Figure 1. A screen shot of the recorded current data view is shown in Figure 2 while significant wave height recorded is shown in Figure 3. The instrument was deployed in the measuring location by the help of professional diver. The ADCP immediately before deployment is shown in Figure 1

State of the Art Acoustic Doppler Current Profiler (ADCP) and Optical Backscatter Sensor (OBS) have been used for Simultaneous Current, Wave

and Suspended Sediment Concentration Measurement in the Coastal Areas


At the same time, turbidity was measured by using Campbell Scientific’s OBS 3A turbidity sensor and sediment samples were collected at the same location and depth of ADCP. The arrangement of turbidity sensor (OBS 3A) along with the sampling pump is shown inset of Figure 1. The sensor is capable of recording in situ Turbidity and also has temperature, conductivity and pressure sensors in built. The sensor was kept fixed above 1m from the channel bed and configured for sampling at 1 second interval for duration of 5 minutes. The data collection interval was set to 10 minutes (5min data & 5min break). Primary objective of the turbidity measurement was to quantify sediment concentrations in mg/l, thus to investigate the amount of bed transport. The sensor is most responsive to the amount of sediment present in the water and the second largest characteristic that affects Turbidity is the size and

shape of sediment in the water. Obtained turbidity from the sensor was then calibrated for sediment after establishing a co-relation between those, as shown in Figure 4. Measured Turbidity data are then converted to sediment concentration from the relationship derived. Calculated time series sediment concentration in mg/l and mean current speed for the measurement period is also shown in Figure 5.

WRP division has been involved quite extensively in various urban water management and drainage related study projects in Bangladesh. Mentionable are those of Dhaka, Chittagong and Sylhet city development of drainage and sanitation, master plan of Chittagong City. Other project includes feasibility study and detail design of a water treatment plant of 50 million litre per day capacity for Sylhet city. The division was involved in the

supervision of implementation of two large water supply projects for Dhaka city: namely Padma (Jashaldia) water treatment plant and Tetuljhora – Bhakurta Well field construction project. These two plants is expected to supply about 600 million liters per day treated water to Dhaka city. In addition, the division has been involved with rural piped water supply projects in various districts of Bangladesh.

It is a great challenge for Sylhet City Corporation (SCC) to ensure water supply in adequate quantity and with acceptable quality round the year. SCC is entrusted with the responsibility to supply potable water to Sylhet Metropolitan City area through its piped network. At present, SCC maintains water supply to the Sylhet City mostly from groundwater and with one 28 MLD capacity surface water treatment plant constructed by DPHE at Kushighat. There are about 38 production wells to cover about 26.5sq. km with around 200 km distribution network. At this stage, existing 28 MLD treatment plant only provides water around 3-4 months and rest of the year the treatment plant cannot be kept in operation due to non- availability of water at intake point. In addition to that, the static water table of the groundwater is declining rapidly because of excessive withdrawal. In the long run, there will be scarcity of drinking water unless alternative sources are explored. To respond to this emerging scenario, SCC has made a strategic decision to shift from ground water source to surface water source, as per direction of the Government of Bangladesh. In this regards, a 50 MLD Surface Water Treatment Plant with

option for phase-wise operations have been proposed with intake at Chamura Kandi at the left bank of the

Sari-Gowain River. IWM has been entrusted to conduct the feasibility study with detail design of the project. The study will look into various options for intake & WTP, assess dependable flow of Sari-Gowain River, select water treatment process, detail design of SWTP and estimate cost of the project etc.

The water quality of the six rivers around Dhaka city (Buriganga, Balu, Turag, Lakhya, Tongi Khal and Dhaleshwari) has deteriorated due to pollution significantly. There are mainly nine sources of pollution. Untreated industrial effluentis the major source in addition to domestic waste water and sewage, solid waste, medical waste, waste from poultry and dairy farms, burnt oil and lube oil from river vessels, construction demolition waste, restaurant and vegetable whole sale market waste. As a result, the rivers are in critical condition, especially in the dry season, when there is

hardly any aquatic life in the rivers due to very low level of dissolved oxygen and high level of different pollutants. DWASA engaged Institute of Water Modelling (IWM) to assist in the preparation of an Action Plan for Control of Pollution of Peripheral Rivers of Dhaka City.

DWASA and IWM are working in developing the action plan for pollution control keeping four strategies in the purview. These are: (1) pollution prevention measures (structural and non-structural), (2) enabling environment, (3) public awareness and mobilization and (4) Rehabilitation and conservation of rivers, khals and other water bodies.

Practical Action Bangladesh engaged Institute of Water Modelling (IWM) to accomplish the project having title “Identification of Char Lands: Pumpkins Against Poverty”. The main objective of the project was to analyze satellite imageries for a period of time in order to find Char Lands in the project area. This project utilized Geographic Information System (GIS) and Remote Sensing (RS) Technologies for comprehensive analyses of the Free and Open Source Satellite imageries in order to identify the Char Lands. In the study, the result from the satellite image analyses are then put into categories such as Permanent and Transitional types. The demographic analysis has also been included to see the impact of the beneficiaries living close to the identified Char Lands. It has been observed that the potential char land in this study area is 2709 Sq. km (average area in 2016-17 period). Generally, this charland is in increasing trend. From four different time spans (2013-14, 2014-15, 2015-16 and 2016-17) the Pearson’s Correlation Coefficient has been found as 0.89 which represents a strong uphill positive linear relationship between area and time. In 2016-17 time span, average permanent char land has been found 1496 Sq. Km and average transitional char land has been found 1213 Sq. Km.The result of this study could be useful for different groups of professionals including policy makers in order to utilize transitional char lands for growing suitable crops. They can also be used for grazing lands for animal

husbandry. The study this way can contribute to the sustainable development through ensuring food security for the poor people living in the project area by utilizing transitional char lands.

more efficiently. It considered integration of IP-Camera, Mobile Apps and advanced GIS and web technologies for remote information access and visual monitoring.In this connection, BWDB assigned IWM to develop a Web-based SiMS (SiMS-Web) under a contract titled “Upgrading, Updating of Existing SiMS and Development of SiMS-Web, SiMS Google & SiMS App for Smart Phone Project”. The assigment was started in May 16, 2016 for one year.The activities were made around the embankment, hydraulic structures, canals and protective works of the completed and on-going schemes. The project encompasses the BWDB’s all projects located within South-Eastern Zone (SEZ), Chittagong covering an area of 21,700 Sq. Km. The SEZ consists of Chittagong O&M Circle and Cox’s Bazar WD Circle.

According to the TOR of the Project, SiMS-Web has been developed with several types of Modules and tools are enabled through Internet. Data were collected in prede-fined forms and both spatial and non-spatial data are stored in Oracle database. ArcGIS Server has been used for GIS map service. The web application was developed using ASP.NET, Java Script APIs and other necessary tools. Cordova has been used to develop mobile apps to enhance BWDB's data collection performance as well as to monitor the real-time data capturing status. For remote and real-time monitoring, alongside the IP-Camera, Skype integration has been done with SiMS-Web.In addition, as a background information, ESRI online map services has been considered in SiMS-Web
