Among the various hazards created by nature on the earth surface, the one caused by flood and river bank erosion is more common and quite devastating. Like, earthquake and volcanic eruptions, it also affects human activities in various ways wherever it occurs. Erosion, transportation and deposition are the main functions of a river. Through these activities, it creates different landforms and brings about changes in its course. When it overflows its banks, it creates natural calamities, like flood, erosion and sedimentation, which adversely affect human occupancies of the floodplain.
