WebOct 16, 2024 · Some part of the precipitation that lands on the ground surface infiltrates into the subsurface. The part that continues downward through the soil until it reaches rock material that is saturated is groundwater recharge. Water in the saturated groundwater system moves slowly and may eventually discharge into streams, lakes, and oceans. Web1) Adhesion provides a matric force (responsible for adsorption and capillarity) that reduces energy state of water near particle surfaces. 2) Osmostic forces: attraction of water to ions and other solutes, tends to reduce energy state of water in soil solution. 3) Gravity: always pulls the water downward.
