Abstract
apping flood-prone areas is one way to control floods in a non-structural way. The area around the Walanae river in Wajo district experiences flood every year and gets the biggest impact from the flood event. This study aims to map flood-prone areas and flood risks according to the area that gets the greatest impact. Analysis of flood-prone areas in this study uses the application of Geographic Information Systems (GIS) with three parameters, namely topographic data, flood volume DEM. The analysis was performed using the scoring and weighting methods. Geographic Information System is used as a spatial model in mapping flood potential using the overlay/intersect technique in ArcGIS10.1 and represent it in the form of a map based on the three parameters used. In this study, a high hazard class value of 8.21% was obtained for Pammana district, 7.49% for Sabbang Paru district and 7.68% for Tempe district.
