Flood Risk Assessment and Management

Located in the Special Capital Region of Jakarta (DKI Jakarta), which serves as the government capital and national capital of Indonesia, the Ciliwung River plays a major role in Indonesia. The increasing population of the Jakarta and Bogor area has resulted in an increase in the level of land ownership, which has had an impact on increasing areas of settlement and decreasing green open spaces. This rapid urbanization and change in land use has directly affected the hydrological nature of the area, causing an increase in the flooding volume in this region. This research was conducted in four stages: hydrological analysis, hydraulic analysis, flood hazard mapping, and flood assessment of land cover. To estimate the impact of the land cover change that has occurred, the Soil Conservation Service Unit Hydrograph was used along with the West Java rainfall distribution method. Hydraulic modeling uses the
