Modeling groundwater recharge
WebThe 5-year model simulation (1/09/2012-31/08/2024) show that 94.44% of precipitation (P) is distributed over the catchment as effective precipitation while 67.53% of P percolates as gross recharge. Most of the water is lost via groundwater evapotranspiration (ET g ), which accounts for 68.74% of P, unsaturated zone evapotranspiration (ET uz Web1 okt. 2024 · Groundwater models can be used to: Evaluate well systems and water resources (yield, drawdown, interference,…) Define capture zones/Wellhead Protection Areas (WHPAs) Assess the environmental impacts from mine dewatering Assess water quantity and water quality issues at mine sites
