Abstract

There are several approaches for Flood hazard mapping and prioritization, but the distributed and GIS-based methods are amongst the best and widely used. On this basis, in this study a new distributed method is applied which considers the interaction between the effective factors. By using a linear combination the Flood hazard map is created for the study area and divided into five classes including very high, high, moderate, low and very low Flooding hazard potential. Verification of this approach by using recorded destructive Floods at different hydrometric stations indicated that the performance of this method, especially on identifying areas with very high and high hazard levels, is very remarkable. For example, the results of Distributed Approach in Shirgah-Talar, Razan-Noor, SoleimanTange, Ghoran-Talar and Doab-Challos hydrometric stations are fully matched with recorded historical Floods most of them have over 50-year and 100-year return periods.
