Talajvíz. A talajvíz az édesvízkészlet azon része, ami a felső vízzáró réteg felett helyezkedik el, és kitölti a talajszemcsék közötti üres teret. Ezen víztömeg felső szintjét talajvízszintnek nevezik, ennek magassága függ a csapadék -, hőmérséklet - és nyomásviszonyoktól .
Definition. Groundwater is fresh water located in the subsurface pore space of soil and rocks.It is also water that is flowing within aquifers below the water table.Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water, and deep groundwater in an aquifer (called "fossil water" if it infiltrated into the ground millennia ago).

Nov 6, 2018 · Groundwater is a part of the natural water cycle (check out our interactive water cycle diagram). 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.
Mar 2, 2019 · It is difficult to visualize water underground. Groundwater is simply the subsurface water that fully saturates pores or cracks in soils and rocks. Groundwater is replenished by precipitation and, depending on the local climate and geology, is unevenly distributed in both quantity and quality to nearby lakes, rivers, and wetlands.
May 21, 2024 · Ground water in its broadest sense includes all subsurface water whether in its liquid, solid or gaseous state, provided it is not chemically combined with the minerals present. In practice, it is all subsurface water that participates in the hydrological cycle. Definition source: United States Geological Survey.
