Identification and validation of potential flood hazard area using GIS‐based multi‐criteria analysis and satellite data‐derived water index

This article identifies potential flood hazard areas through multi‐criteria analysis in Allahabad district, India. The study has incorporated eight criteria, namely, flow accumulation, draining capability, elevation, groundwater depth, land use, runoff coefficient, slope, and geology for preparing hazard index.

The authors suggest that the GIS‐based multi‐criteria decision analysis (MCDA) method can be very effective for mapping flood hazards that may be beneficial for decision making in flood management. The methodology employed here can also be applied for data‐limited areas anywhere in the world.
