Flood Risk and Vulnerability of Addis Ababa City Due to Climate Change and Urbanization

Since 1988 Addis Ababa is increasingly affected by flooding. The rapid economic growth of the city increases the urbanization rate significantly, furthermore, an increase in summer season precipitation is expected with a possible risk of flooding. In this research, we analysis the flood risk and vulnerability due to climate change and urbanization using Soil and Water Assessment Tool. The change on peak flow is quantified after careful calibration/validation and uncertainty analysis considering two landsat images and General Circulation Models. The model result indicated that a 10% and 25% increase in peak flow due to climate change and urbanization respectively.
