An integrated approach for the improvement of flood control and drainage schemes in the coastal belt of Bangladesh
<BASEFONT SIZE="2"><font size="""2" FACE="Arial" COLOR="#000000">During the past decades huge investments have been made in flood protection, drainage and irrigation schemes to reclaim and develop many polder areas in Bangladesh. In these areas a careful water management is required to get optimal results from the investments in the physical infrastructure and enable the farmers to have a better living. However, in many instances the actual water management in the Flood Control and Drainage (FCD) schemes has been below expectation, resulting in lower yields than were envisaged during the feasibility, design and construction stages.<br/></font><font size="""2" FACE="Arial" COLOR="#000000"><br/></font><font size="""2" FACE="Arial" COLOR="#000000">In order to formulate suitable water management strategies for this type of areas research has been conducted in a pilot</font><font size="""2" FACE="Arial" COLOR="#000000">polder 43/2A. In the framework of this research water management strategies and practices have been developed in consultation with the farmers considering the needs of agriculture, fisheries, navigation and environment. As per requirement in the field and considering the results of the hydrodynamic simulations, a new water management strategy has been developed. This strategy is designed to achieve the maintaining of preferred water levels during the year which will give optimal benefits that were not thought of earlier. The strategy has been prepared to match the normal practice of the farmers. This has also resulted in recommendations for land use zoning, linked to topography, soil and water management conditions. Based on the developed criteria and water management strategy a land suitability analysis has been performed for the present and potential conditions in polder 43/2A.
