| During recent years, increasing exploitation of groundwater aquifers has caused a substantial and sharp drop in groundwater table in the plains of Iran. Artificial discharge of aquifer using flood spreading in plains is an approach that has been implemented in many parts of the country so far. In this method, by flowing flood into the aquifer, will control flooding and soil conservation. In addition, increasing the volume of the reservoir and preventing a sharp decline in groundwater level do the same work. This research has been used to integrate the AHP / Fuzzy model in order to evaluate suitable land for flood spreading in the Shourdasht watershed in the Ghahavand, Hamadan province. To this end, after the selection of effective indicators in the location of these areas such as slope, permeability, alluvial thickness, transmission capacity, flooding, and hydraulic conductivity, using the analytical hierarchy process (AHP) were weighted and their importance was identified. The fuzzy method was used to normalize the effective measures in the zoning of flood spreading areas. Then, based on the integration of fuzzy layers, a final map of the land suitability for locating the flood spreading areas was determined. The results showed that in the relevant classification it was found that 42.46% accounted for completely unsuitable, 19.27% in the classes with a moderately suitable, and finally 37.78% were in a suitable and completely suitable class. | ||
