water that fills the cracks and spaces in underground soil and rock layers
zone of saturation
lower region of groundwater where all the pore spaces in a rock or sediment are filled with water
the upper surface of underground water; the upper boundary of the zone of saturation
a body of rock or sediment that stores groundwater and allows the flow of groundwater
Natural replenishment of an aquifer by precipitation, which percolates downward through soil and rock.
water contained in places such as lakes, ponds, rivers, streams, and reservoirs
Water flowing off the land into bodies of surface water.
An ecosystem where all water runoff drains into a single body of water
Surface runoff of water that generally can be counted on as a stable source of water from year to year.
total amount of freshwater humans remove from a rive, lake, or aquifer
water use in which the water is not returned to the environment in a liquid form; for example, irrigation leading to evaporation
a use of water where the water is immediately available for reuse
water hot spot
identified areas in the U.S. where competition for scarce water could trigger intense political and legal conflicts
the removal of salt from seawater to make it usable for drinking and farming
charging such a low cost for water that there is no incentive to conserve
water is pumped to the fields and is allowed to flow along the ground among the crops
a proccess by which pipes placed near plant roots drip only as much water as the plants need.
Water usually pumped from underground and sprayed from mobile boom with sprinklers.
a method of landscaping that uses plants that are well adapted to the local area and are drought resistant, reduces water useage.
tiered water pricing system
a system in which the required amount of needed water costs very little, however increases of water use cost increasingly more money
The area subject to flooding during a given number of years according to historical trends.
soil moisture detectors
indicates soil moisture, enabling farmers to cout their irrigation water use by 33-66%
all of the wastewater that drains from washing machines, sinks, dishwashers, tubs or showers and can be reused for non-sanitary purposes
Movement of salt water into freshwater aquifers in coastal and inland areas as groundwater is withdrawn faster than it is recharged by precipitation.
allows scientists to identify the origins, age, size, flow, and fate of water in aquifiers
A system of bridges and canals that carries water from place to place.
straightening of a river/stream to reduce upstream flooding; typically results in water moving through area faster and causing more flooding downstream
raised banks along a stream channel that increase velocity, upstream risks and create false security to live by bodies of water likely to flood
a process used to separate dissolved solids from a liquid, which is boiled to produce a vapor that is then condensed into a liquid
A desalinization process that involves forcing salt-water through a membrane permeable to water but not to salt
a well drilled through impermeable strata into strata that receive water from a higher altitude so there is pressure to force the water to flow upward
Serious water shortages are emerging as the demand for water in many countries simply outruns the supply forcing people to live in poverty.
Unplanned slum development on the margins of cities, dominated by crude dwellings and shelters made mostly of scrap wood, iron, and even pieces of cardboard.
The gradual sinking of land. The condition may result from the removal of groundwater or oil, which is frequently instrumental in supporting the overlying rock and soil.
the scattering of chemicals into clouds to bring about rain
World's largest aquifer; under parts of Wyoming, South Dakota, Nebraska, Kansas, Colorado, Oklahoma, New Mexico, and Texas (the Midwest). Holds enough water to cover the U.S. with 1.5 feet of water. Being depleted for agricultural and urban use.
