Abstract:
A simplified water balance model consisting of 15 parameters and using daily rainfall and monthly pan evaporation as input was tested for application on semiarid watersheds. The model structure consists of three moisture stores. Runoff is calculated as a function of soil moisture excess and a daily loss rate which is calculated by a modified Horton infiltration equation. All but one parameter were either eliminated from the study or estimated from soils data. The remaining parameter, the shape factor in the modified Horton equation, was adjusted to fit the model to the mean annual flow on five experimental watersheds in Tombstone, Arizona. The fitted values of the parameter were correlated with watershed characteristics. The relationship found in the correlation was used to validate the model on six different experimental watersheds. The results of both the calibration and validation were then compared to the SCS Curve Number method and a rainfall-runoff regression equation developed from data for one of the calibration watersheds.
