Overlying groundwater
WebMay 19, 2024 · Most groundwater comes from precipitation. It seeps into the ground and begins to saturate the soil underneath. The groundwater fills in any and all available spaces in the soil and underground ... WebGroundwater can also return to the surface. The level of the water table in an unconfined aquifer influences the volume of water in surface drainage channels that flow across it. When erosion removes overlying layers or cuts deeply into the earth's surface, the groundwater in aquifers can be brought closer to the surface.

Groundwater is stored in the open spaces within rocks and within unconsolidated sediments. Rocks and sediments near the surface are under less pressure than those at significant depth and therefore tend to have more open space. For this reason, and because its expensive to drill deep wells, most of the groundwater … See more Porosity is the percentage of open space within an unconsolidated sediment or a rock.
