A Study on the Production of Vulnerability Map for Floods Using GIS and RS

Abstract

Recently, floods have been increasing due to rapid urbanization and human activity in lowland. The research investigating the reason of floods that are caused by overflows and collapses of the banks of the Nakdong basin. The purpose of this study is to extract the multi-factor related to flood hazard concerning geomorphologic characteristics, land cover, and runoff régime. For the multiple criteria valuation technique, we choose multiple factors and determine their relation and how they impact the flooding areas.
