WebThe potentiometric map also provides clues about the rate of groundwater flow. If you think back to Darcy material and our in-class activity from last week, you will recall that groundwater flow rate depends on the head gradient (i.e. the hydraulic gradient) and hydraulic conductivity. WebSome streams and lakes intercept the water table, allowing direct groundwater–surface water exchange. The potentiometric surface reflects the water pressure of a confined aquifer, and is the level to which water in a well will naturally rise (i.e., to an elevation above the confined aquifer it penetrates).
