Insights From a Multi-Method Recharge Estimation Comparison Study
WebJun 12, 2024 · Nine separate groundwater recharge estimation methods, with a total of 17 variations, were applied at a shallow aquifer in northwest Ethiopia in the context of the potential for shallow groundwater resource development. These gave a wide range of recharge values from 45 to 814 mm/a. WebFeb 16, 2024 · In arid and semi-arid climates, some component of modern groundwater recharge was detected in all studies, with median values of 60 mm (IQR 30–140 mm) and 200 mm (IQR 90–430 mm) respectively decade −1, although recharge rarely occurred every year but was episodic (e.g. Taylor et al 2013b ). 顔 押すと痛い
