Abstract

Tangerang City was largest city in Banten Province with total area of 184.23 km2. Tangerang City was generally combination of coastal areas with lowlands condition which is located along Cisadane River. Mapping of flood-prone areas in Tangerang City aims to identify areas which have potential for flooding, so these areas can be analyzed for preventing action. In this research, flood-prone areas were identified using scoring method. The flood parameters consist of land height, slope, rainfall, soil type, land cover, and river range. Spatial information was represented in form of map, while attributes of spatial information were represented in tabular form using different parameters and weight values in mapping flood hazard in Tangerang City. The results show us that level of flood hazard in Tangerang City was divided into four classes of hazard, namely level of flood hazard "safe"in Benda District with area of 0,831 Ha, level of flood hazard "slightly vulnerable"in Jatiuwung District with area of 155,897 Ha, level of flood hazard "Prone"occur in Pinang District, which has area of 1.360,161 Ha, while level of flood hazard "very vulnerable"was in Benda District, which has area of 1.358,454 Ha.
