Development of flood risk map at Kuantan using geographical information system
The purpose of this study is to develop the flood risk map in Kuantan. The heavy prolonged rainfall in Kuantan has showed an increasing flood disaster over a year. Geographical Information system (GIS) is integrated with AHP is used to generate the potential flood risk area. Flood map was develop by...
