Flood Exposure of Settlement Areas in Bekasi City

Abstract

Flooding is one of the hydrometeorological disasters that often-hit Bekasi during rainy seasons. Flood in Bekasi is caused by its topographical characteristics and poor drainage condition. As Jakarta's buffer zone, the mobilization inhibition of Bekasi people will impact economic activities in Jakarta. Therefore, a mitigation measure is needed to reduce losses. This research aims to map the flood exposure of Bekasi's settlement areas as a reference for mitigation action. The level of exposure in this research is analyzed by assessing rainfall, land use, slope, altitude, drainage conditions, and distance from rivers. This exposure mapping uses remote sensing data based on Geographic Information Systems (GIS). The results show that Bekasi's settlement areas prone to flooding are in sloping areas, areas near the river, and areas with poor drainage conditions. These areas include the South Bekasi Subdistrict, East Bekasi, North Bekasi, West Bekasi and Rawalumbu.
