Abstract

This study presents a new method for incorporating rainfall into landslide modelling and prediction. The method involves 3 steps : compiling radar reflectivity data in a QPESUMS (quantitative precipitation estimation and segregation using multiple sensors) system during a typhoon (tropical hurricane) event, estimating rainfall from radar data and using rainfall intensity and rainfall duration as explanatory variables to develop a landslide logit model. Given the logit model, this paper discusses ways in which the model can be used for computing probabilities of landslide occurrence for a real-time monitoring system or a warning system, and for delineating and mapping landslides
