The mode) presented here calculates the soil water balance given input measurements or estimates of climate, soil properties, and vegetative cover conditions. The input data requirement is kept to a minimum in order to maximize the utility of the model in situations where few measurements are available. Model sensitivity to error in input values is(More)
