This paper presents on a new lumped model for estimation of flood flow from mountainous river watershed. First, the new model is made up of the storage area with the retarding area, the stream reach and the translation reach is proposed. Then, the technique for identification of the model parameters and the procedure for estimation or prediction of flood runoff by the model is introduced. Finally, the model is applied to three mountainous river watersheds, and a validity of the concept of rainfall-runoff process in the model and an availability of the model to mountainous river watersheds are discussed.
