Calibration & Validation of HEC-HMS Parameters for Kharkai River Basin

The rainfall runoff process is one of the most frequently used events in hydrology. It determines the magnitude of runoff which leaves the watershed resulting from the rainfall received by the basin during a particular period of time. Numerous methods have been developed by different researchers to simulate the rainfall runoff process for different watersheds. But the most commonly used tool to estimate the basin’s hydrological response to precipitation is hydrological modeling. Rainfall runoff model is such a model which is used to simulate the rainfall- runoff process in a basin. It helps to compute runoff volume peak runoff rate base flow loss rate by simulating the hydrologic activities involved in the process.
