Modeling of Flood Propagation in the Lower Citarum River Using a Coupled 1D-2D HEC-RAS Model
Lower Citarum experiences recurring flood that caused by extreme rainfalls. Study of flood models is now needed to anticipate and prepare flood risk management to reduce losses. This study presents the modeling of the Lower Citarum flood flow using 1D-2D flood modeling in HEC-RAS to understand the behavior of floods. A combination of topographic survey and satellite data was used to model the river channel. Fifteen lateral structures were used to couple the 1D and 2D regimes, where the locations of the structure were based on observations. Results showed minor excesses over the lateral structures, which gradually grow into large areas over time. The study identifies locations with a high risk of flooding in the Lower Citarum Zone, which can be used in further studies for academic and practical purposes. The model result has a discrepancy with the observed data. This difference probably occurred due to the different analysis methods between the observed data and flood modeling or the model’s accuracy.
