In order to use overland and stream flows of watersheds, flood control is a basic water resources management step especially in arid and semi-arid areas. Selecting suitable areas for flood spreading is one of the most important parameter in the success of the concerned projects. The aim of this study was to evaluate the accuracy of index of overlay maps, Boolean and fuzzy methods to identify the flood spreading areas, using GIS techniques. For this purpose, five geographical information layers including slope, land use, surface infiltration, quaternary units and aquifer depth were interpolated based on the three presented approaches. The results (as the output maps) were evaluated and compared with the field control sites. The results showed that the method of Multi class maps, because of its maximum overlaying surface with the control sites, comparing to the other models was the best method for the selection of flood spreading sites in the Poshtkoh Basin, Iran.
