Analysis of Rainfall Thresholds for Geologic Hazards in Mei-zhou City Based on E-I-D Model

Abstract：This paper investigated the characteristics of rainfall-induced landslides during the flood season in Mei-zhou City and its warning threshold model,and analyzed the main roles of short-term intense rainfall and long-term moderate rainfall infiltration in landslide events.By comparing the I-D,E-D,and E-I models,it was found that it was difficult for a single model to comprehensively predict landslide risk.For this reason,this paper constructed the E-I-D model,which took rainfall intensity,duration,and effective rainfall into account to improve the accu-racy and comprehensiveness of landslide prediction.The model was adapted to the monsoon climate characteristics of Meizhou City and provided theoretical support for the optimization of the early warning system for regional land-slides and the prevention and control of geological hazards.
