Abstract :

Indiscriminate exploitation of groundwater aquifers in the arid and semi- arid regions plains0f Iran has been causing a sharp drop in groundwater levels. artificial recharge groundwaterby flood spreading Method is a procedure that applicable for increasing the volume of thetank and prevent the severe drop in groundwater levels. In this Study Identificated suitableareas of flood Spreading for artificial recharge groundwater by using integrated GeographicInformation System(GIS) and Analytical Hierarchy process(AHP) in Abied- Sarbishe 0fGotvand region. For this seven effective indices - slope, infiltration, electrical conductivity,alluvial thickness transmisivity, drainage density and land use was prepared in GISenvironment and weighted by Analytical Hierarchy process(AHP). In next step with usingGIS analytical function and weight of each layer in AHP Method integrated effective indicesmaps and prepared finally map in four classes from suitable to unsuitable. The results of thisstudy showed That areas with high suitability for artificial recharge projects Often in alluvialfan geomorphological units and often located in less than 3 percent slopes.. Ground controlsshowed that high compliance between site selection and projects implemented in the studyarea.
