Assessing the efficiency of Analytical Hierarchy Process and Frequency Ratio models in flood susceptibility mapping.

Abstract

Floods are the most devastating natural disasters that causes massive damages to natural and man made features. Flood susceptibility mapping is an essential step for implantation of flood management strategies using different models with the help of GIS and Remote sensing technique. Despite of numerous models used in flood susceptibility mapping, this study was conduct to articulate the most efficient model from the two commonly used i.e. frequency ratio and analytical hierarchy process. The specific objectives of this study was to model flood susceptibility using two different models and to compare the accuracies of maps produced by both models using Receiver Operating Curve.
