Abstract:
Detailed evaluation of the Water Erosion Prediction Project (WEPP) Watershed Model hydrologic component was performed using hydrologic data from three small semi-arid watersheds located within the USDA Walnut Gulch Experimental Watershed in southeastern Arizona. Evaluation includes both calibration and validation procedures. Favorable results were obtained when the model was calibrated. The parameter estimation procedures within the WEPP model did not produce accurate estimates. Peak rainfall intensity simulated by the rainfall disaggregation model was less than the observed data, causing simulated runoff to be lower. The peak runoff rate simulated by the approximate method was higher than values simulated by the kinematic wave model. Cumulative distribution curves of simulated runoff were significantly different the observed curves, due to model's inability to accurately simulate the runoff of smaller events. On the small watershed used in this study, transmission losses were relatively insensitive to changes in channel hydraulic conductivity.
