Abstract: Due to the ever-increasing demand on water resources, the pressure on its judicious utilization is also increasing. Besides being precious, this resource is also complex to manage on account of its dynamic behaviour. It implies that the response to a unit of precipitation input is dependent on the state of wetness of the land mass and the environment prevalent at that time. Therefore, the changing weather conditions as well as the spatial variability of land mass result in nonlinear behaviour of the response of the watersheds.
