Study on the Relation of Storage-Discharge Model to Channel Net work Characteristics

Abstract

Various types of the lumped runoff model have been treated for practical uses. For example, the so- called storage function model, i.e. the model based on storage-discharge relationship, has been widely accepted. The characteristics of the storage function model have been examined empirically in several of the actual watersheds. These have also been discussed theoretically with the help of the kinematic wave method on the mountainside. However, in the channel regions, the discharge depends on the characteristics of the channel networks. This paper shows that parameters of the storage function model can be estimated by the characteristics of channel networks and the flow velocity.
