降雨型浅层滑坡危险性预测模型
A Model for Predicting Rainfall-Induced Shallow Landslides
摘要
Abstract
The method that combines a hydrologic model and GIS for predicting rainfall - induced shallow landslides is practicable. The limitations of the SHALSTAB and the TRIGRS models are discussed. In order to improve the SHALSTAB model, a simplified transient hydrologic model is proposed based on the dynamic conservation of rainfall mass. This model involves long term rainfall history, rainfall process and simplified saturated- unsaturated seepage. The SHALSTAB model is the special condition of this model. With the infinite slope model, transient hydrologic model and GIS system, an integrated model for predicting rainfall - induced shallow landslides is proposed. And with this model the hazards risk of shallow landslides can be assessed by the geological, topographical and rainfall conditions.关键词
