Abstract | The study deals with the evaluation of water balance of Ping river basin in Thailand. A physically based conceptual lumped parameter model NAM is used to achieve this objective. The model is calibrated by trial-and-error method to find the value of parameters involved using the daily streamflow, evaporation and rainfall data of period 1973 to 1975. Verification of predictive capability of model is done by using the data of period 1976 to 1978. Both in calibration and verification periods the hydrograph configuration, water balance and simulation of peak are found to be satisfactory. Different hydrologic components of water balance such as overland flow, interflow, actual evapotranspiration, ground water recharge and streamflow are computed during calibration and verification period. It is observed that there is large variation in basin yield in different hydrological years. Due to the fluctuation of surface water and groundwater storages, the streamflow is not equal to the difference between the mean areal rainfall and actual evapotranspiration. |
