A GRID-BASED KINEMATIC DISTRIBUTED HYDROLOGICAL MODEL FOR DIGITAL RIVER BASIN

摘要：

A grid-based kinematic overland flow routing model for rainfall-runoffmodeling was developed for flood forecasting. The watershed was sub-divided into a raster system for representing the spatial variability of soil, vegetation and rainfall, etc. In each grid, hydrological processes such as interception, infiltration and overland flow were considered. Runoff generated in each grid was routed by a kinematic wave method according to the digital river basin extracted by using DEM by DigitalHydro software package. The model was applied to Shiguanhe river basin. The model was able to reproduce runoff volume and peak discharge with high efficiency.
