Water resources management in Bangladesh faces immense challenge for resolving many diverse problems and issues. The most critical of these are alternating flood and water scarcity during the dry seasons, ever-expending water needs of a large population, growing economy, and massive river sedimentation and bank erosion (Ministry of Water Resources, Government of Bangladesh, National Water policy, Dhaka, 1999).
There is a growing need for providing total water quality management (dealing with surface water salinity in the coastal areas, deterioration of surface water and groundwater quality, and water pollution), and maintenance of the eco-system. There is also an urgency to satisfy multi-sector water needs with limited resources, promote efficient and socially responsible water use, delineate public and private responsibilities, and decentralize state activities where appropriate. All of these have to be accomplished under severe constraints, such as lack of control over rivers originating outside the country’s borders, the difficulty of deltaic plain, and the virtual absence of unsettled land for building water structures (Ministry of Water Resources, Government of Bangladesh, 1999).
