Web18 jun. 2024 · Groundwater recharge estimation (GRE), particularly at a regional scale, is an important challenge in hydrogeology. Unsaturated zone flow (UZF) modeling is now being used increasingly for GRE, though its validity relies on the accurate estimation of the soil hydraulic parameters (SHPs). In this study, a regional spatial-nonstationarity-based … Webgroundwater level of a groundwater reservoir by artificial means. Due to highly complicated hydrogeological conditions, the modeling studies on groundwater …
