To address the lack of information on the spatial and temporal variability of recharge to groundwater systems in Maine, a study was initiated in cooperation with the Maine Geological Survey to use the U.S. Geological Survey Soil-Water-Balance model to evaluate … WebJan 26, 2015 · Landscape and soil conditions also influence the relationship between mean annual GWR and GWL depth (Fig. 5). Simulation results show that mean annual GWR increases with depth only to a certain limit, w p , and can be approximated with the Pashkovskii equation (Shestakov et al., 1982): p ( 0 ) exp z p ( γ ) w(z) = w − w −w − (18) …
