Abstract

Locating suitable areas for the construction of flood spreading structures and infiltration into underground aquifers for the purpose of storing runoff and increasing groundwater reserves to supply the water needed for various purposes and to control flood damage, Highlights the importance and necessity of these studies in protecting natural and human resources. In this study, it has been attempted to provide suitable locations for flood spreading in Khorramabad watershed. For this purpose, parameters: land use, elevation, drainage density, geology, distance from residential areas, river distance, distance from road, slope, soil classes, soil texture, electrical conductivity and unsaturated thickness were measured in ArcGIS10. 5. . At first the parameters were fuzzy-fuzzy between zero and one, and then, using hierarchical analysis, pairwise comparison of the variables was quantitatively classified, and then using Expert Choice software based on AHP method, Weight of each criterion was obtained. The most effective criteria in this study were the parameters of distance from residential areas, land use and unsaturated thickness. Finally, using ArcGIS10. 5 techniques and linear-weight combination, the location for flood propagation was determined. The results showed that according to the final map of flood spreading, 13. 99% of Khorramabad watershed has appropriate utility and 26. 04% of moderate utility for constructing flood spreading structures. These areas can be considered in planning the actions needed for flooding in the area.
