| Project Name:
Rapid Assessment of Hydrology, Morphology and Pollution of Rivers and Canals around Dhaka. |
| Country: Bangladesh |
| Project Duration: 06/2020 to 05/2021 |
| Description of Project:
Recognizing the salience, magnitude and complexity of the issues relating to rivers and canals around Dhaka, their restoration was identified as a priority in the Bangladesh Delta Plan (BDP2100); and the Government of Bangladesh (GoB) commissioned a River Master Plan (RMP) to guide the process. The RMP was completed in June 2019 and proposes a multi-phase program of interventions for the ecological restoration of rivers and canals around the city. Financing for implementation of RMP is proposed to be arranged through budgetary allocations as well as through support from Development Partners (DPs). The World Bank is proposing a potential engagement (“Ecological Restoration Support to Rivers and Canals around Dhaka” Project) to support the restoration agenda, with co-financing from other DPs, IFIs and private sector. The project area comprises with 5 major rivers namely Buriganga, Sitalakkhaya, Turag, Balu and Dhaleshwari rivers and 39 canals in and around Dhaka. Total length of the river is about 410Km. |
| Description of Actual Services Provided by Staff of this Firm in the Assignment:
The scope of work includes: Task 1: Undertake preliminary Hydrology and Morphology study on 5 rivers around Dhaka § Flow dynamics of Buriganga river, Turag river, Shitalakhya river, Dhaleshwari river and Balu river. § Sediment characterization, assessment of sediment transport and transport of dissolved solids § Assessment of catchment characteristics and the channel network which influence runoff processes § Geometric assessment of rivers including Bathymetric info § Assessment of channel patterns and channel forms including water surface slope, water velocity and riverbed materials, etc. § Assessment of environmental flow requirement Task 2: Undertake desk review on river pollution which will include pollution type, cause, sources, mitigation measures and potential location of ETPs § Identification of point and defuse sources of pollution § Estimation of volume of pollutant discharge into rivers § Estimation of number of the ETPs required to intercept and divert and development of options Task 3: GIS Mapping of river boundary, canals, bridges, vulnerable areas § Identification of river boundaries based on satellite image and BIWTA river boundary info (existing and actual) § Identification of locations required dredging and excavation- Vulnerability Mapping § Identification of canals (existing and actual) § Mapping of sources pollution, transport path and potential location of ETPs Final rapid assessment report on hydrology, morphology and pollution of River and canal around Dhaka |
