Abstract:
Evaluation of a water yield model developed by Williams and LaSeur, with modifications suggested by Hawkins, on southwestern watersheds. Calibration and validation of the model were accomplished using 1963 to 1970 data from three selected subwatersheds of the Walnut Gulch Experimental Watershed. An International Mathematical and Statistical Library Program was used to calibrate the model on a portion of data, to determine the initial parameters. Validation of the model was accomplished by using the second portion of the watershed data and the initial parameters determined from the calibration for prediction. Results show that model overpredicted discharge on all three subwatersheds by varying amounts, with little consistancy in the amount of variation between the measured and predicted discharge explained. Stratification of storms by season, on one watershed, to try and account for the overestimation of discharge, showed a 10 percent increase in the variation of discharge explained. Model still overpredicted the discharge but not as greatly.
