Flood Hazard Modelling in Jakarta Using Geomorphic Flood Index

To prevent and minimize flood damage and causes, crucial information like the location or area that are exposed to flood is needed. DEM (Data Elevation Model) will be processed to obtain more data such as Flow Accumulation and Flow Direction and more by using ArcGIS Pro, which then will be used in the Geomorphic Flood Area plugin’s for calculation and prediction in QGIS (Quantum Geographic Information System). Data that will be used in this paper are gathered from Demnas for the Data Elevation Model, which in this case is using Interferometric Synthetic Aperture Radar as their topographic mapping technique. The goal of this research is to utilize said available plugin and obtain the depiction of flood prone areas in Jakarta, while comparing the accuracy of the Special Capital Region of Jakarta’s flood history data, with the processed one.
