HYDROLOGICAL MODELING WITH HEC-HMS FOR WAN RESERVOIR CATCHMENT
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 51
Abstract
Hydrological modelling is a mostly used appliance to estimate the basin’s hydrological response to precipitation. HEC-HMS model is used to simulate rainfall-runoff modelling for catchment of Wan reservoir, Akola, Maharashtra. To compute runoff, Peak runoff rate, base flow and flow routing methods SCS curve number, Clark unit hydrograph, Recession and Muskingum-Cunge routing methods were chosen, respectively. Rainfall runoff simulation is conducted using 33 rainfall event data. Out of these, 12 events were selected for model calibration, 09 for model validation and remaining 12 for prediction. To judge the performance of model, statistical tests of error functions like Root mean square error (RMSE), Nash Sutcliffe coefficient ( ) and coefficient of residual mass (CRM) were selected. Curve number (CN), Initial abstraction (Ia), Time of concentration (Tc), Initial base flow (Qo), Recession constant (Rc), and Threshold flow (Qt) were the model parameters which were fixed as 61.47, 32.20, 10.50, 5.07, 6.38, 1.0 and 0.25, respectively, for catchment of Wan reservoir. The model performed well in terms of RMSE, , CRM (1.40 mm day-1, 0.89 and - 0.11). Considering the performance of model in simulating the runoff, it is suggested that the calibrated HEC-HMS model could be used to predict runoff for the rainfall events over catchment of Wan reservoir.
