  • 摘要:Central Sulawesi is the largest province on the Sulawesi island with a dominant sloping topographic condition. It has a variety of soil types, flow density, land use, and rainfall that makes this region vulnerable to flooding. Flooding is a hydrometeorological disaster that will adversely affect aspects of human life such as social and economic activities in an area because it can cause environmental damage, casualties, and disrupt economic activity. Because of its enormous impact, the purpose of this research study is to find out areas in the province of Central Sulawesi that are susceptible to flooding. The method used in this research study is scoring the classification of flood hazard parameters such as slope level, elevation, soil type, rainfall, land use, and low density which then overlay all the parameters. The results are obtained that the province of Central Sulawesi has three categories of areas susceptible to flooding with a low category 6630.3 km2, moderate 46081.9 km2, and high category 7104.7 km2. Based on the results and discussion, it can be concluded that Central Sulawesi province has a moderate dominant level of vulnerability.
