How is groundwater able to flow upward

WebWater falling on the ground surface as precipitation (rain, snow, hail, fog, etc.) may flow off a hill slope directly to a stream in the form of runoff, or it may infiltratethe ground, where it is stored in the unsaturated zone. WebGroundwater flow generally is from areas of recharge to areas of discharge, in the direction of decreasing water-level altitudes and perpendicular to the water-level altitude contours. Water-level altitude maps and regression analysis were used to determine shallow groundwater-flow directions and gradients in the Skagit River Delta area.
