Abstract

Flood vulnerability analysis was conducted in the Lubuk Kumbung Area and Surrounding Area, North Musi Rawas Regency, South Sumatra as a follow-up study on geological mapping that had been conducted previously using district spatial data, DEMNAS data. These data were developed into parameters used in vulnerability analysis including slope parameters, flow density, soil type, rainfall, and land use. Based on the calculation results for each parameter used, several results were obtained. In the slope parameter, the research area is dominated by a slope of 15-25% with an area percentage of 34.20% and a total value of 15. Furthermore, in the flow density parameter, the research area has a flow density of 0.80 with a total value of 12. Then the soil type parameter is dominated by the regosol type with an area percentage of 48.97% with a total value of 3. In the rainfall parameter, the research area has an annual rainfall of 3500-4000 mm with a total value of 6. Furthermore, land use as the last parameter is dominated by mixed dry land agricultural land with an area percentage of 48.89% and a total value of 8. The results of the calculation and analysis of flood vulnerability in the research area are divided into five classifications where the research area is dominated by a fairly vulnerable classification with a total area of 41.47² km with an area percentage of 51.81%. Then followed by a rather vulnerable classification with an area percentage of 35.14% and a vulnerable classification covering an area percentage of 11.98%.
