From very ancient period, civilization and river are very closely associated. River leads impact on life style of the people of its bank area. However, the dimension this relation has changed through time. The objective of study is to understand the behavior of river and its relationship of its inhabitants. The fact is that the study has two segments; first is to assess the behaviour of the river that is the morphological properties of river and the next is the socio economic aspect of river which is directly related to human being.This comprehensive study is divided in to five chapters. The first and second chapters consist of historical back ground of Dwarekeshwar River and morphological attributes in details. The third and forth chapters consist of all attributes of human recourse and the economy with special emphasis on flash flood. Last chapter included the present and future prospect of the Dwarekeshwar river basin (in reference to surface runoff). The morphological study of river needs to be analyzed and the unique characteristics of each river should be understood only by the morphological properties of the river. The planning, design and construction practices in respect of river training and anti-erosion works are based on empirical or semi empirical study. Indiscriminate use of formulae regarding water planning, without regard to the unique characteristics of a river, sometimes lead to an anomalous situation where the benefits from a river training work are to some extent off-set by its ill-effects on the river regime. For a scientific and rational approach to different river problems and proper planning and design of water resources projects, an understanding of the morphology and behaviour of the river is a pre-requisite. On the basis of this principal, the details morphological analyses have done here. The most remarkable identity of Dwarekeswar River is that, it consists of transitional characteristics of both flash floods it its upper catchment, monsoonal flood in the middle and tidal effect in its lower confluence simultaneously. Here it is important to mention that river Dwarekeshwar comes from an area which has a chronic drought history with scanty of rainfall and flows through the area which has chronic flood history. This river does not meet to Bay of Bengal independently. It meets river Hooghly 240 km (150 miles) away from the Bhagirathi’s estuary. Its meeting point is quite far from the estuary of the river Bhagirathi but in spite of that this area is tidal (meeting point of Selai and Dwarekeshwar near Ghatal). This thrice combination (flash flood in upper catchment with the zone of scanty of rainfall, middle is the zone of monsoonal flood and the lower confluence is dominated by tidal effect) of Dwarekeshwar river is unique one. The study has also incorporated the impacts of the sand and gravel mining from the Dwarekeshwar river bed.
