Abstract: A simple nonlinear model is described which has several advantages over the traditional unit hydrograph technique. The catchment is divided into several subcatchments, the storage characteristics of which are represented by conceptual stores of S = kQm. The value of the exponent, m, is found to be reasonably constant in practice. The model was applied to two catchments in Victoria, Australia, and found to perform well. The chief advantages of such a model are that it allows catchment and rainfall variability to be modeled and that it easily accommodates the case where gaging stations are remote from proposed dam sites.
