Evaluation of Landslide Susceptibility Using Scientific Investigation and Quantitative Evaluation

Abstract

Landslide disasters in steep slopes in urban areas are increasing due to climate change. In Korea most of the steep-slope disasters are induced by typhoons and torrential rains in the Summer time, causing many casualties, property damages, and recovery costs. In order to response this disaster it is imperative to implement the scientific site investigation on potential slope areas and evaluate their vulnerability quantitatively. The efficient maintenance and management of steep slopes often require excessive professional resources and quantitative investigations. Therefore, it is important to develop a technology for the objective scientific site investigation and quantitative evaluation for steep slopes. In this study we proposed Evaluation system which evaluates the stability analysis of steep slopes and provides a vulnerability level.
