The book explains the reasons of flood and its influence in the socio-economic development in the District of Murshidabad, West Bengal, India. Sustainable management of flood in the district has been analysed scientifically on the basis of authentic data sheets and deep research work.The tectonic evaluation of any landscape is made on the basis of hypothesis. The tectonic evaluation of the terrain also helps to determine that whether the area is suitable for planning and development or not. It is undoubtedly said that the fertile Ganga-Brahmaputa delta is suitable for agricultural purposes but the low flat terrain is suitable for agro based industries also. The minerals can be achieved from the womb of it and can be filled up by the sands available here to maintain sustainability. The low flat terrain is enriched by ground water also, thus the people of this region will not suffer from scarcity of water. The only enemy of the deltaic region is the destructive flood. If the flood is controlled here in a sustainable manner then the world's largest delta will remain as one of the as one of the world's largest densely populated region for ever.
