Site Suitability Analysis of Shelters for Dam Break Flood Hazard Using Gis

Rajalakshmi CR, Thulasidharan Nair

Emergencies occur at unpredictable places at unexpected time. During unexpected emergency situations, where there are no existing shelters, evacuation is done to local facilities which serve as temporary shelters. The temporary shelters should satisfy certain criteria to be deemed suitable. Prioritizing the shelters based on their suitability prior to an emergency save a lot of time during evacuation and it helps the authorities to attend to the various needs of evacuees during their temporary settlement. In the present study an effort is made to classify available shelters in the study area based on their site suitability in the face of a disaster. Here we are considering shelters for temporary evacuation from Dam Break flood. Analytic Hierarchy Process (AHP) is used for assigning weights to each parameter used for shelter selection and site suitability is found through Weighted Linear Combination (WLC) method.
