SECOND SMALL SCALE FLOOD CONTROL, DRAINAGE AND IRRIGATION PROJECT

Guidelines for Preparation of Subprojects (SSFCDI Works)

I. Introduction

1.01 Proforma have been designed to assist in assembling technical infor-mation required for the preparation of identification and feasibility:eports. Different project components, consisting of fully planned sub-projects and appurtenant structures subprojects (including rehabilitation andrepair works) would have different standards for acceptance. Separateproforma have been designed for these components.

1.02 The procedure to be adopted is given below:

(a) Identification reports for all subprojects prepared by BWDB fielddivisions, as described in proforma detailed below and discussed withthe Superintending Engineer of the Circle, would be submitted to thePIU for review. PIU would be assisted by CTU and the FFW Unit in theFlood Control Cell of BWDB.

(b) Identification reports on proposed rehabilitation and repair workswould have sufficient data to enable PIU to present these subprojectsat the five-party meeting to be scheduled for September of each year(Proforma One). At this meeting, decisions would be taken to proceedwith detailed engineering.

(c) Identification reports on proposed appurtenant structures subprojectswould have sufficient data to enable PIU to prepare a feasibilityreport (Proforma Two) and present it to the five-party meeting ofSeptember, recommending that it proceed with the detailed engineeringof the subprojects.

(d) Identification reports on proposed fully planned subprojects wouldhave sufficient data to enable PIU to recommend that the subprojectsadvance to the feasibility phase (Proforma Three).

(c) Shadow wage rates for labour should be the average prevailing ratesweighted by the approximate length cf season over which they prevail.This rate should be discounted by the factor 0.75 to revalue it in borderTaka.

(d) Investment and O&M costs should be exclusive of taxes, duties and pricecontingencies. Local costs should be expressed in bordet Taka afterapplying SCF of 0.8. Capital cost of minor irrigation equipment shouldnot be included, but its O&M cost would be part of the farm budget. Landacquisition costs for the economic analysis would be the value of produc-tion foregone due to withdrawal of land from agricultural use and shouldnot be included separately in the analysis.

SECOND SMALL SCALE FLOOD CONTROL, DRAINAGE AND IRRIGATION PROJECT

Consultancy Services during Implementation (FRW)

Terms of Reference

Background

1. Flooding is a normal feature in Bangladesh's life and is caused bysnowmelt in the upper catchment areas of the Ganges and Brahmaputra riversand by monsoon rainfall in the lower catchments. Snowmelt reaches a peak inJune resulting in heavy runoff in July and August. About 80% of the annualrainfall, ranging from 125 cm in the southwest of Bangladesh to more than 500cm in the northeast, occurs in the five-month period, May through September.There are, however, very large variations in annual rainfall. In years ofheavy flooding, major crop losses and damage to infrastucture occur.

2. A major flood disaster took place in July-September 1987 and thereported damages appear to exceed those experienced for at least the last 25years. Over 50,000 sq km are reported to have been inundated affecting apopulation of over 30 million and causing damage to crop, property, livestockand infrastructure, estimated at about US$550 million. The 1987 floods werecaused by a combination of unusually heavy rainfall from July through Septem-ber and the simultaneous rise in water levels in the rivers due to uppercatchment flows. Rainfall d'iring August was reportedly two times abovenormal in most locations. According to the Ministry of Relief andRehabilitation no less than 1,200 km of BWDB's flood embankments, 640 watercontrol structures, 220 km irrigation canals and 40 km of town protectionworks were fully or partially destroyed. Damages to roads, bridges, cul-verts, and school buildings also reached unprecedented levels.

3. In response to a GOB request for assistance in financing therehabilitation works, IDA would support two complementary programs: (a) afreestanding credit which would finance priority works during the FY88 con-struction season; and (b) inclusion of a component in the proposed SecondSmall Scale Flood Control, Drainage and Irrigation Project to ensure con-tinuation and completion over about three years of the rehabilitationactivities. Both programs would include technical assistance components forproviding consultancy services during implementation.

BANGLADESH

SECOND SMALL SCALE FLOOD CONTROL, DRAINAGE AND IRRIGATION PROJECT

Mathematical Modelling Studies of River Sections Protectedby the Brahmaputra Right Embankment (FRW)

Guidelines for Preparation of Terms of Reference

Introduction

1. The Brahmaputra is a braided river, without fixed banks and withfrequently shifting channels. The river originates from the northern slopesof the Himalaya range in Tibet, and has a total length of approximately 2,700km. The average ye arly discharge is 20,000 mJ/s; the maximum recorded dis-charge is 91,000 m at Bahadurabad. The sediment transport amounts to 600million tons per year. In Bangladesh the total river width varies between 6and 15 km. During low flow stages, from November till April, the flow isconfined in a number of channels. The number of channels varies between oneand six. Channels shift frequently and the situation in one year may becompletely different from the next year. Shifting river channels erode theriverbanks from time to time.

2. The irahmaputra Right Embankment (BRE) was constructed between 1963and 1970 over a length of about 170 km along the right bank of theBrahmaputra river to protect adjoining lands against yearly floods, occurringbetween June and October. The BRE has been constructed at some distance fromthe western bank of the Brahmaputra, in order to have a buffer zone whichwould delay the erosion of the embankments in case of channel shifts.

3. Ideally the BRE should only be subject to loadings resulting fromdifferential water levels on both sides, and from moderate current velocitiesoccurring in the flood plain of the Brahmaputra during high river stages. Ifan outflanking channel of the Brahmaputra is eroding the riverbank and isencroaching upon the embankment, thus reducing the width of the buffer zone,it will eventually erode the embankment as well. In that case additional(retired) embankments have to be made, whereby the existing embankment andthe previous buffer zone between embankment and river channel is abandoned.Numerous sections of retired embankment have been made so far.

-36- ANNEX 4

Page 2

4. The Brahmaputra seems to have a general tendency to shift westward.This westward trend is more pronounced in certain reaches and possibly absentin others. In the past, substantial areas of land have been (or had to be)"sacrificed" to the Brahmaputra. This practice was largely based on economicconsiderations. The cost of river works, able to arrest the movement of theBrahmaputra, would by far exceed the value of the lands saved from the ero-sion. Moreover new land emerges elsewhere in case of a river or channelshift. Not everywhere the river was allowed to erode the buffer zone and/orembankments. Near the town of Sirajganj, for instance, substantial bankprotection works were carried out. A groyne was also constructed north ofSirajganj in order to deflect the flow of the main channel of the Brahmaputraaway from the western bank.

5. At many locations retired embankments have been constructed to atotal length of some 100 km over the past 20 years. Erosion is causingserious problems at the ferry crossings, where terminals have to be shiftedas a result of eroding river banks. To resolve these problems, investiga-tions are presently undertaken by the BWDB and the River Research Institute(RRI), which include field measurements and model testing. However, theinvestigations have no bearing on a development plan for the whole river.

6. Other river studies are being carried out in relation with the JamunaBridge Project. Although these studies are mostly limited to the area closeto the bridge, some aspects definitely are useful for the envisaged BREstudies, but need to be extended. The practice of abandoning the buffer zoneand original embankments may however not be acceptable in the future because:

(a) important population areas (among others a district capital and anumber of upazilla headquarters); and

(b) essential infrastructural works, among which a number of paved feederroads, will in the near future be threatened by progressing rivererosion. Apart from the "plain" economic value thereof, the socialproblems related to the uprooting/displacement of the population aresubstantial and cannot be valued in simple economic terms.

7. The damages to agriculture, infrastructure, buildings and houses,together with the cost of repairs and construction of retired embankments,have become unacceptably high. Therefore a thorough study is required toanalyze the feasibility of a rigorous approach towards protection of the BREwith adequate and durable river works. The cost and implications of such anapproach should be compared with the present situation and practices.

8. Against the sketched background, GOB is planning to commission astudy which should provide recommendations for:

(a) improved performance of the BRE as flood (protection) embankment; and

(b) permanent protection of the BBE against river erosion.

-37- ANNEX 4Page 3

Scope of Study

9. General recommendations for improved performance oi the BRE andpermanent measures against river erosion can only be given after thebehaviour of the Brahmaputra, its individual channels and features of theflood plain are thoroughly studied and understood. To this end the consult-ant has to gain sufficient insight in the following aspects/phenomena:

(a) characteristics and behaviour of the river channels and channelpatterns;

(b) geomorphological and geophysical aspects of the Brahmaputra floodplain;

(c) medium and long term changes that can be expected in the generalcourse and characteristics of the river, of its channels and channelpatterns;

(d) effects of river works, bank protection and embankments, which havebeen constructed in the past, on the behaviour of the river;

(e) causes of past breaches of the BRE;

(f) effects of future river training schemes/works on the rivermorphology and hydrology; and

(g) agricultural practices, land use, present infrastructure and thedamages that would occur if the BRE would not function adequately.

10. Having studied the above aspects/phenomena, the consultant shallpropose and/or work out;

(a) possible measures for an improved performance of the existing BRE,and their technical and economic feasibility;

(b) river training schemes suitable for the permanent protection of theBRE, including Lhe effects to be expected on the environment; opera-tion and maintenance aspects shall be taken into considerations aswell;

(c) an implementation schedule for physical/other measures proposed under(b) above; the schedule shall be flexible and shall allow for thephased implementation of permanent river works.

11. In support of the above, the consultant shall carry out hydrographicand topographic surveys and shall employ mathematical and physical modelsinsofar as necessary and practical to support the river studies and designs.

12. Key Data and Conditions for Present River Study. The consultantshall become familiar with past studies carried out in relation with theBrahmaputra. The consultant shall in particular become familiar with, e.g.,study, hydrological, geo- and river-morphological and hydraulic aspects ofthe Brahmaputra, its tributaries and distributaries including:

-38- ANNEX 4

Page 4

(a) river discharge and water levels;

(b) rainfall and drainage patterns of adjacent areas;

(c) wind-developed phenomena, such as wind waves;

(d) sediment transports and bed forms (including variations duringhydrological cycles);

(e) characteristics of individual channels, channel patterns, formationand movement of river bends, bifurcations and confluences and relatedsiltation and scour processes;

(f) historical changes of the river and of river channels and prognosesfor future developments, using aerial photographs and sateliteimageries;

(g) geotechnical conditions along the Brahmaputra, including seismicity;

(h) geomorphological and geological aspects of the Brahmaputra flood-plain; and

(i) land and agricultural use, including irrigation and drainage prac-tice, infrastructural facilities and developments, including road,rail and water transport.

13. Inventory and Analysis of Past Works. The consultant shall preparean inventory of past construction and maintenance works, including retiredembankments, and its effects, in which the following shall receive specialattention:

(a) breaching as a result of overtopping;

(b) breaching as a result of progressing river erosion; and

(c) breaches created on purpose by the population with a view to solvedrainage and other problems.

An assessment should be made of the speed and type of erosion, and the soilcharacteristics at each location.

14. Master Plan for Containment of the Teesta and Brahmaputra Rivers.The consultant shall prepare a master plan for the containment of the tworivers from downstream of the Teesta Barrage down to Brahmaputra's confluencewith the Hurasagar. The master plan shall include recommendations for thetype and layout of river training works aiming to provide a permanent protec-tion of the BRE. While preparing the master plan, the consultant shallconsider whether any measure proposed for fixation of particular points orstretches along the rivers will not have any detrimental effect elsewhere.In the master plan the consultant shall also indicate which physical measuresshould be implemented on a priority basis, and which measures could bedefered till later. The consultant shall have regard for the time required

-39- ANNEX 4Page 5

for arranging financing, etc., and for the implementation of the measuresproposed.

15. The master plan shall also address possible alternatives for riverworks/measures. Cost estimates of river works and maintenance required shallbe incorporated in the master plan, along with an investment schedule forphased implementation of the physical measures proposed. As a basis for themaster plan, the consultant shall carry out the necessary hydrological andriver morphological analyses and studies.

Short Term Measures

15. In order to implement an immediate rehabilitation of criticalsections of the BRE, priority areas shall be identified on the basis of thethreat posed by the river erosion. Population centres, important infrastruc-tures, agricultural losses, cost of remedial works and scope of variousalternative measures, shall be the criteria for the selection of the sitesand the type of measures (retired embankments with or without permanentprotection works) to be implemented immediately. The short term rehabilita-tion and/or construction of river works have to be incorporated in the masterplan for development of improved flood protection along the Brahmaputra.

Detailed Design

16. Simultaneouly with the development of the master plan, the consultantshall prepare designs for river works, taking into account:

(a) constructibility;

(b) maintenance aspects; and

(c) likelihood of failure and consequences thereof.

Where possible and practicable, the consultant shall allow in his designs fora maximum use of local labor and materials. In designing the river worksthe consultants shall give special consideration to the following:

(a) scour levels at critical locations, including bed scour caused byphenomena such as:

(i) river bends;(ii) confluence of channels;iii) local scour (introduced by, for instance, groynes).

(b) current velocities, including abrasive action caused by suspendedsediments;

(c) flow slides (subsidence slides) and liquefaction of subsoil as aresult of earthquakes;

(d) possible extension of the works in the future; and

¢ (e) construction, planning and scheduling.

Model Investigations

17. As a basic support to the river studies the consultant shall usemathematical and physical models suitable to stimulate the flow of water andsediments of the Brahmaputra, and foreseeable changes therein, resulting fromboth natural phenomenon and man-introduced measures or actions.

Surveys

18. The consultants shall arrange for the collection of river data,additional to the data routinely collected by the BWDB and BIWTA, par-ticularly during high river stages. Systems for accurate positioning ofsurvey vessels are considered essenti&l for obtaining reliable data.

Tender Documents

19. After completion of the detailed design, the consultant shall preparetender documents for the works to be implemented, which shall follow asclosely as possible the World Bank Sample Bidding Documents for Procurementof Works, dated September 1986. If and when required by the Bank, the con-sultant shall advice on the pre-qualification of contractors capable ofimplementing the works.
