عنوان مقاله [English]
The formation and subsequent recharge of alluvial aquifers depend on the geological conditions, geomorphology, climate, and land cover.This type of aquifer plays main role in supplying the water needed by human societies in arid and semi-arid regions of the country and mainly due to excessive perceptions, they require the development and implementation of management plans. 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.
