Abstract :

In recent years, striking the balance between water supply and demand, reducing precipitation, climate change and, consequently, reducing surface water resources, the utilization of groundwater resources is more likely than past to be considered. Overuse and unmanaged use of groundwater resources in most plains of the country, especially in Hashtgerd Plain, has created a critical situation so that we can see the groundwater level decrease. Preservation of existing underground water resources, in a situation where the country is in a semi-arid region, in addition to providing water demands, in the landscape, it increases the hydrogeological potential of the soil. reduction in water levels will increase energy consumption and the cost of harvesting and extracting water, reducing water quality, land subsidence, increasing soil erosion and, more importantly, the emergence of a strategic water resource loss is increasing in the future. The purpose of this research is to manage and optimize the conjunction utilization use of surface water, underground and unconventional water in order to reduce the surface water deficit of Hashtgerd aquifer based on Integrated Water Resources Management to supply existing water demands, with the least harmful effects on the quality of groundwater resources and land capacities within the range.
