Floods can play great havoc including loss of life, damage to property and agricultural crops, health hazards and disruption of human. The information such as peak flow and its volume are required in the design phase of irrigation, hydro-power and flood control projects. Hydrological models are widely used for the computation of flows in response of precipitation in the catchment and help to understand the characteristics behavior of a stream over a long period of time. The inputs for such models include long term records of stream flow, meteorological data and catchment characteristics. This...
