A STUDY ON THE SUPPORT OF MANAGEMENT FOR SLOPES AND EVACUATION FROM SLOPE FAILURES USING SLOPE-GIS

Abstract

It is difficult to find the necessary information on slopes expediently, because most of the information on slopes is recorded only on paper documents. In this study, we constructed a GIS database that consists of disaster reports collected in the past 24 years and general survey data on the slopes. We also proposed a slope failure management support system to find slopes with potential failure risk and to recall past recorded disasters, as well as slope failure warning and evacuation system to support decision-making based on GIS database. Furthermore, these systems are defined as “Slope-GIS”.
