The present study is concerned with the geomorphological knowledge in management of dams and barrages special reference to Farakka barrage in West Bengal. Dam is the barrier constructed across a stream or river to impound water and raise its level. A barrier of concrete or earth built across a river to create a body of water as for domestic water supply. A reservoir of water creates by such a barrier. A barrage is a construction across a water course to increase the depth of water to assist

Both of these are build up for the purpose of equal water distribution, irrigation, proper navigation, reduce flood level, generation of hydroelectricity, decreasing siltation in the lower coarse of the river etc. So management of dams and barrages is also essential. In this case geomorphological knowledge as a management tool plays important role like Remote Sensing and GIS. Because the geomorphological knowledge help to overcome the different problems created by the construction of dams and barrages. Farakka Barrage is a barrage across the Ganges River, located in the Indian state of West Bengal, roughly 10 kilometres (6.2 mi) from the border with Bangladesh near Chapai Nawabganj District. So the over says problems shows in West Bengal and surroundings as a result of construction of Farakka barrage. Geomorphological knowledge like idea of soil, geology, hydrology etc. as management tool of dams and barrage is very significant. INTRODUCTION:
