[1] Groundwater can be created by using dewatered aquifer space to store water during the years when there is abundant rainfall. It can then be pumped and used during years that do not have a surplus of water. [1]
Water balance in a basin. A general water balance equation is: [ 5] P = Q + ET + ΔS. where. P is precipitation. Q is streamflow. ET is evapotranspiration. ΔS is the change in storage (in soil or the bedrock / groundwater) This equation uses the principles of conservation of mass in a closed system, whereby any water entering a system (via ...

Figure 7. Runoff from the water balance. The recharge, also called effective rainfall or rainfall excess, can be modeled by a pre-reservoir (figure 6) giving the recharge as overflow. The pre-reservoir knows the following elements: a maximum storage (Sm) with unit length [L] an actual storage (Sa) with unit [L] a relative storage: Sr = Sa/Sm
