Abstract

Application of Geographic Information System (GIS)For Study of Flood in Denpasar City Denpasar city in general situation has flat area, high rain fall intensity and the dominated landuse of settlement. This condition can reduce the catchment area. This leads Denpasar City become potential for the occurrence of flooding. Therefore, it needs to do research about flood occur in Denpasar.The aim of this research is to find out level of flood vulnerability and it’s spatial distribution in Denpasar. Weighting, scoring and overlay method were used in this research. There are six indicators were analyzed using Geographic Information System (GIS) such as landused, rainfall, type of soil, slope, altitute and drainage density.The result of this research is a map of flood vulnerability in Denpasar City. There are four class of flood vulnerability. Total of the area classified as low, medium, high and very high of flood level are 0,225 hectares (0,002%), 251,73 hectares (2,11%), 4686,7 hectares (38,91%), and 7107,08 hectares or 59% rispectively.
