The objective of this study was to evaluate of the Tank model in simulating runoff discharge from rural watershed in comparisonto the SWAT (Soil and Water Assessment Tool) model. The model parameters of SWAT was calibrated by the shuffled complexevolution-university Arizona (SCE-UA) method while Tank model was calibrated by genetic algorithm (GA) and validated. Four damwatersheds were selected as the study areas. Hydrological data of the Water Management Information System (WAMIS) and geologicaldata were used as an input data for the model simulation. Runoff data were used for the model calibration and validation. The determinationcoefficient (R2), root mean square error (RMSE), Nash-Sutcliffe efficiency index (NSE) were used to evaluate the model performances.
The result indicated that both SWAT model and Tank model simulated runoff reasonably during calibration and validation period.
For annual runoff, the Tank model tended to overestimate, especially for small runoff (< 0.2 mm) whereas SWAT model underestimaterunoff as compared to observed data. The statistics indicated that the Tank model simulated runoff more accurately than the SWATmodel. Therefore the Tank model could be a good tool for runoff simulation considering its ease of use.
