Abstract

The paper discussed the present state of flood at a junction point between two rivers at Bandar of Ghatal block in Gangetic delta and proposed a technological solution to reduced vulnerability of flood. While annual floods have the potential to wreak havoc on unprepared communities, spoil crops and endanger food security, they also play a vital role in agriculture. Flood Management and Mitigation is designed to minimize negative flood-related impacts while preserving the benefits. Flood mitigation involves the managing and control of flood water movement, such as redirecting flood run-off through the use of floodwalls and flood gates, rather than trying to prevent floods altogether. It also involves the management of people, through measures such as evacuation and dry/wet proofing properties for example. The prevention and mitigation of flooding can be studied on a number of levels: individual properties, small communities and whole area or towns or cities. The costs of protection rise as more people and property are protected. The most effective way of reducing the risk to people and property is through the production of flood risk maps. Most countries in the developed world will have produced maps which show areas prone to flooding events of known return periods. By identified areas of known flood risk, the most sustainable way of reducing risk is to prevent further development in those known flood risk areas. It is important for at-risk communities to develop a comprehensive Floodplain Management plan. Those communities that participate in the National Flood Insurance Program must agree to regulate development in the most flood prone areas. Communities should assign a floodplain administrator to oversee the management of the floodplain development permit process. Reduction of erosion hazard we can use by MZWA (Mapping and zoning of watershed area), RZB (Restricted Zone of Build up), various soft engineering techniques and other necessary methods without any negative impacts of natural resources.
