Abstract

Jakarta has experienced many floods in the past, and those floods resulted in not only human casualties but also economic damages. The aim of this paper is to check a newly available bathymetry of 5 m resolution from ALOS by using a developed flood inundation model whether this fine resolution DEM can be useful to reproduce a better simulation result in Jakarta. The 5 m resolutions show the river width more detail than 30 and 90 m resolutions but a high building in a target area was not captured well in any DEM. As the result of analysis, it was found that there are no significant differences between simulation results using 90, 30 and 5 m DEM resolutions because these DEMs were obtained from satellite images and show no big differences in accuracy.
