GIS BASED LANDSLIDE STABILITY AND HYDROLOGICAL DISTRIBUTION COUPLED MODEL
地理信息系统支持下的滑坡-水文耦合模型研究

Rainfall and geomorphology play an important role in the landslide occurrence. Landslide stability and hydrological distribution coupled model built in this paper is a physical deterministic model that can be easily used in landslide hazard analysis and prediction in GIS. It couples the general limit equilibrium method and hydrological distribution model based on DEM. Comprehensive landslide stability analysis criteria is also established. The modeling results show high accuracy based on the model verification and validation.
