“…In addition of the satellite rainfall data, the distributed hydrological model required initial values of river discharge data and topography. We obtained river discharge data from Water Resources Agency of Jakarta (Dinas Sumber Daya Air Provinsi DKI Jakarta), topography data (digital elevation model, flow accumulation and flow direction) were obtained from Hydroshed with a spatial resolution of 400m over the Ciliwung river basin [1].…”

“…Continuing our previous study [1], the gridded rainfall data and combined it with the distributed hydrological model were applied in order to develop the flood early warning system at Jakarta and surrounding regions. In this paper, the gridded rainfall data derived from satellite rainfall data are used as an input for the distributed hydrological model, the simulation results obtained from the model are expected to describe the inundation which will be occurred over the Ciliwung river basin, as one of the important river basins in Jakarta.…”

Recurrent flooding in Jakarta and surrounding areas due to extreme rainfall is simulated by using distributed hydrological model. In the previous studies, the Rainfall-Runoff Inundation (RRI) model has been used for the flood simulation with 1-km spatial resolution, but it has not been comprehensively investigated. In this paper, extreme rainfall data derived from satellite rainfall data of GSMaP, topography, and land derived from the satellite remote sensing data are used as an input for the RRI model. We analyse the flood simulation at Ciliwung River Basin during 6 (Six) periods of extreme rainfall during January – March 2022 and divide between Flood (F) and Non-Flood (NF) periods. We found that the inundation occurred when the rainfall average reaches more than 7.3 mm/hr and concentrated in the Jakarta downtown area, which had induced the inundation around the Ciliwung river basin.
