Frequent droughts and their consequences result in the loss of groundwater, the deficiency of nutrients, the drying of surface water resources, and substantially more exploitation of the groundwater resources, which, altogether, cause the mobilization of saline waters to groundwater tables. This will impair the capacity of the aquifers and the quality of the water. The VIKOR method was applied ...
