Free Ground Water: Unconfined ground water whose upper boundary is a free water table.
Confined Ground Water
In hydrologic terms, ground water held under an aquiclude or an aquifuge, called artesian if the pressure is positive.
Confluence ...

Ground WaterIn hydrologic terms, water within the earth that supplies wells and springs; water in the zone of saturation where all openings in rocks and soil are filled, the upper surface of which forms the water table. Also termed Phreatic water.
(2) The rate, usually expressed in cubic feet per second, or million gallons per day per mile of waterway, at which ground water enters an infiltration ditch or gallery, drain, sewer, or other underground conduit.
No water table exists if the ground water is confined by an overlying impermeable stratum, as in the case of artesian ground water. Water year Any twelve-month period, usually selected to begin and end during a relative dry season.
Effluent SeepageIn hydrologic terms, diffuse discharge of ground water to the ground surfaceEffluent StreamIn hydrologic terms, any watercourse in which all, or a portion of the water volume came from the Phreatic zone, ...
Phreatophytes Derived from the Greek word "phreatos" meaning well or underground water, this term refers to types of plants with extensive root systems that utilize water from the underlying water table.
''The ground was able to retain some of it, so it will improve the moisture andhopefully improve the ground water,'' Mashek said.
This type of subsidence can similarly be caused by extraction of other resources, e.g. ground water, petroleum or rock salt.

WATER BUDGET - A practice in hydrology where an amount of water in reservoirs, lakes, and ground water is tracked based on rainfall, drought episodes, re-evaporation, and usage by man.
Meteorologists monitor the extent and severity of drought in terms of rainfall deficiencies. Agriculturalists rate the impact on primary industries, hydrologists compare ground water levels, ...
