Flood hazard assessment and mapping using GIS integrated with multi-criteria decision analysis in upper Awash River basin, Ethiopia

Abstract Floods have destroyed people’s lives as well social and environmental assets. Flooding is becoming more severe frequent a result of climate change an increase in human-induced land-use changes, which puts pressure on river channels causes changes morphology. The study was aimed to assess flood danger map inundation areas Ethiopia’s Teji watershed, prone flooding. basic flood-producing factors this were derived from soil, slope, elevation, drainage-density land use cover data. opinions public institutions expert decisions gathered determine the weight analytic hierarchy process. collected data processed using ArcGIS environment method produce map. According findings study, approximately 43.28 13.09% area vulnerable high very risk zones, respectively. As result, prediction, early warning management practices could be implemented regular sustainable basis.
