Flood is an abnormal progressive rise in the water level of a stream that may result in the over flowing by the water of the normal confines of the stream with the subsequent inundation of areas which are not normally submerged.This book highlighted the flood risk reduction management by integrated approach of transboundary river basin planning of India and Bangladesh. Ichamati River is such a river that flows through India and Bangladesh and also forms the boundary between the two countries. The river is facing the problem of siltation leading to thin flow of water in the dry season and floods in the rainy season. Experts are handling the situation and remedial matters are being discussed between the governments of India and Bangladesh. Govt. of India has also raised different issues regarding this river with Bangladesh Government through the Joint River Commission (JRC). The alternate proposal given above will not involve Bangladesh; hence Govt. of West Bengal can immediately take up the project without waiting for an understanding with Bangladesh.
