Abstract

This paper describes the development of an inundation process model integrated with a basin-scale distributed hydrological model. Inundated water levels were calculated with continuous equations of the reservoir with H-V and H-A relations in the area, in which the excess rate of surface flow above the maximum conveyance capacity of rivers is treated as an input to the inundated areas. The performance of the distributed water circulation model in terms of calculated discharges showed that the peak discharges and their timing of occurrence were improved by incorporating the inundation process model. <br>
