Abstract: Recently, humans have been susceptible to a growing number of natural hazards, the most severe and frequent of which is flooding. This study aims to prepare flood hazard risk zone maps of Hyderabad District based on MCDM-AHP method and RS-GIS tools. Various parameters like physiographic, climatic, LULC and pedological were used and thematic maps were prepared from various sources, which were integrated into the ArcGIS software to identify flood hazard zone based on weighted overlay method. Each parameter has given a relative weightage depends on their significance, and sub-class of each parameter was given ranking from 0 to 5. The resultant flood risk map is classified into low, moderate and high-flood risk zone and the result was verified further using past flood events occur in the area. This study can be useful to the planners and local authorities in developing flood prevention and mitigation strategies in Hyderabad District.

Keywords: flood susceptibility zones; analytic hierarchy process; AHP; weighted overlay analysis; WOA; geographical information system; GIS; remote sensing.
