Abstract

The Identification of flash flood vulnerability was carried out in the Bantarsari and surrounding areas, Pabuaran District, Sukabumi Regency, West Java using district spatial data, DEMNAS data and previous research data in the form of geological mapping conducted by Ramadhan (2022). These data were developed into parameters used in vulnerability identification including parameters of slope, flow density, soil type, rainfall, and land use. Based on the calculation results for each parameter used, several results are obtained. On the slope parameter, the study area is dominated by a slope of 15 – 25% with an area percentage of 34.20% and a total value of 15. Furthermore, for the flow density parameter, the study area has a flow density of 0.80 with a total value of 12. Then the soil type parameter dominated by regosol types with an area percentage of 48.97% with a total value of three. In the rainfall parameter the study area has an annual rainfall of 1500 – 3000 mm with a total value of four. Furthermore, land use as the last parameter is dominated by dry mixed agricultural land with an area percentage of 48.89% and a total value of eight. The results of the calculation and analysis of the flash flood hazard in the study area are divided into five classifications where the study area is dominated by a moderately vulnerable classification with a total area of 41.47² km with an area percentage of 51.81%. Then followed by a slightly vulnerable classification with an area percentage of 35.14% and a vulnerable classification covering an area percentage of 11.98%. The simulation also illustrates the potential for overflow on the Citampian River.
