Abstract
Runoff models can be divided into two groups: distributed parameter models and lumped parameter models. These two groups of models have been developed independently. The relationships between these two models were studied in the early 1970's. Since then, many types of storage function runoff models have been derived from the Kinematic Wave model and the unsaturated flow model. However, the characteristics of the various storage function runoff models have not been evaluated sufficiently. This paper focuses on the Kinematic Wave model and three storage function runoff models derived from the Kinematic Wave model and shows the evaluation method based on the frequency response and the stochastic response.
