Alluvial aquifers in the  Gilan-e- gharb have been equilibrium due to favorable environmental conditions until the mid-1970s.But gradually, due to human interference in the hydrology cycle of the region and the occurrence of dry periods, the Gilan-e-gharb aquifer falls to the surface and requires the formulation and implementation of management plans.In this research, modeling of alluvial aquifer susceptible habitats was performed based on six lithology parameters, linear density, drainage density, geomorphology, land use and slope. About 23.8% of the area has a high groundwater abundance potential and 44% of the area has a low potential for groundwater and these areas are prone to runoff. Therefore, the special geomorphological and lithological conditions of the area have caused the natural recharge of aquifers to be limited and requires the implementation of artificial recharge plans.
