Abstract: In this paper we propose a novel approach for flood hazard mapping by processing and analyzing a time-series of satellite data and derived flood extent maps. This approach is advantageous in cases when the use of hydrological models is complicated by the lack of data, in particular high-resolution DEM. We applied this approach to the time-series of Landsat-5/7 data acquired 2000 to 2010 for the Katima Mulilo region in Namibia. We further integrated flood hazard map with dwelling units database to derive flood risk map.
