A STUDY ON THE METHOD FOR DETERMINING CRITICAL RAINFALL IN A SEDIMENT COLLAPSE DUE TO NATURAL FACTORS

Abstract

We construct a judgment system on the collapsible and noncollapsible sediment in a disaster, due to rainfall and natural torrential factors. The system examines the influential factors on the collapse of sediment in a disaster and some problematic points are brought under scrutiny in forecasting it. We present a prevention control of disaster for each torrent by applying a method in the judgment system for determining the critical rainfall of sediment collapse.
