Estimation of Spatial Groundwater Recharge Using WetSpass Model For east Wasit province ,Iraq

Groundwater is an important water source, especially in arid and semi-arid areas. Recharge critical to managing analyzing groundwater resources despite estimation difficulty due temporal spatial change. the study aim estimate annual recharge for eastern Wasit Province, Iraq. Where suffers from a surface shortage region's high elevation above Tigris River by about 60 m. It necessary search alternative sources, such as use, with increased demand light of growth oil extraction region, where requires quantity three times amount extracted. The result shows calculated using WetSpass model period (2014-2019) ranged 0 65.176 mm/year at rate 27.117 standard deviation 21.498. simulation results reveal that simulates components hydrological budget correctly. For planning available resources, better grasp long-term average geographical distribution around balance beneficial.
