Document Summary
Infiltration (sweeping into ground) absorption and downward movement of water into the soil. Run off flow of water leaving an area through surface or subsurface. Aquifer: a natural underground storage medium for groundwater, types: (1) unconfined open to earth"s surface and infiltration (2) confined overlain by less permeable materials (3) perched underlain by low-permeability unit (4) artesian water rises some. Aquiclude: an impermeable body of rock or stratum of sediment that acts as a barrier to the flow of groundwater. Perched water table: develops where impermeable rock exists beneath an aquifer. 3 zones: soil water belt zone of aeration, unsaturated zone zone of percolation, ground water zone of saturation. Water table: the upper limit of the body of ground water, varies with precipitation, outflow and removal. Factors affecting distribution and availability of ground water. Ability of ground surface to allow water to infiltrate. How are lakes and wetlands related to groundwater. Wetlands at the water table or perched.
