The general relationships between these and the nomenclature for a river transect are summarised in Figure 6.2. high porosity When producing a potentiometric map for confined aquifers, it is generally appropriate to exclude head data from deeper wells located in the recharge and discharge areas so the flow lines will represent flow parallel to the aquifer boundaries. Each system has wells, a treatment plant, elevated storage tanks, and distribution piping. In large regional studies, where head changes in the down gradient direction are large, transient head errors may not impact interpretations of flow directions and fluxes because changes are small (a few centimeters) compared to the spatial variation in heads (meters). Groundwater discharge to rivers takes many forms, including preferential groundwater . The rate of recharge is also an important consideration. 2). Processes of aquifer recharge and discharge can occur both naturally or be influenced by human activity.
