This study aims to develop a flood hazard susceptibility map for the Cuttack district in Odisha, India, using a combined Analytical Hierarchy Process (AHP) and fuzzy logic framework. Eight spatial parameters were used to generate weighted flood susceptibility surfaces. The AHP method is used for assigning weights to various flood hazard criteria: slope (16%), elevation (17.7%), drainage density (14%), rainfall (15.7%), distance from roads (2.8%), distance from rivers (6.2%), Topographic Wetness Index (TWI) (16.5%), and Land Use Land Cover (LULC) (10.2%).
