6 Managing Water Supplies flashcards

Front

wetlands

Back

Areas where water covers the soil, or is present either at or near the surface of the soil all year or during periods of the year

Front

groundwater seepage

Back

When excessive amounts of groundwater push to the surface as a spring or an area of saturated soil

Front

soil moisture

Back

the amount of water found in the soil

Front

permeable

Back

A material that allows liquid to pass through is (sandstone is a permeable rock type)

Front

water table

Back

An underground boundary between the soil surface and the area where ground water saturates the in the rocks

Front

discharge zone

Back

The zone where water originates from the land surface or unsaturated zone into an aquifer out into water courses such as lakes, rivers and wetlands

Front

natural recharge

Back

Water that moves from the land surface or unsaturated zone into an aquifer. Where porous rock at the surface allows water to seep into an aquifer.

Front

confined aquifer

Back

An aquifer below the land surface that is found between layers of impermeable material

Front

aquitard

Back

A zone within Earth that restricts the flow of groundwater from one aquifer to another; comprised of either clay or layers of non-porous rock

Front

artesian well

Back

Underground water is under pressure. When punctured by a well or borehole the water will rise to the surface.
