Dünyanın tatlı suyunun %68'inden fazlası buzda ya da buzullarda kilitlidir; ve diğer %30'u yeraltı suyudur. - Over 68 percent of Earth's freshwater is locked up in ice and glaciers; and another 30 percent is in groundwater.
Water that is held in the rocks and soil beneath the surface of the Earth Ground water feeds wells and springs
Water beneath the earth's surface that fills pores between materials such as sand, soil or gravel Groundwater is a major source of water for agricultural and industrial purposes and is an important source of drinking water for about half of all Americans
Water under the earth's surface that supplies streams, rivers, wells and springs
Groundwater is that subsurface water contained in the interconnected pore spaces below the water table of an aquifer Groundwater will occur where there is an impermeable subsurface barrier that allows water flowing through the unsaturated zone to be collected and stored within the interconnected pore spaces at depth This impermeable barrier may be bedrock or an impermeable layer of rock Once collected in the saturated zone, groundwater will flow from areas where the water table is highest toward areas where it is lowest This percolation of water through the saturated zone is powered by gravity Eventually, percolating water may leave the groundwater system and be discharged into streams or other surface water bodies
Water contained underground in the earth's saturated zone Groundwater supplies wells and springs
Water in the subsurface which is beneath the water table and thus present within the saturated zone In contrast to water present in the unsaturated, or vadose zone which is referred to as soil moisture
water beneath the earth's surface that fills underground pockets (known as aquifers), supplying wells and springs
Underground water that fills pores in soil or openings in rocks to the point of saturation Where groundwater occurs in significant quantity, it can be used as a water supply
The supply of fresh water found beneath the surface of the Earth (usually in aquifers) that often supplies wells and springs (Source: Carbon Dioxide Information Analysis Center, 1990)
Water beneath the surface of the earth which saturates the pores and fractures of sand, gravel, and rock formations
the fresh or saline waters found beneath the earth's surface that often supply wells and springs Contrast to 'surface water'
(1) Water occurring below the soil surface that is held in the soil itself (2) Subsurface water, or water stored in the pores, cracks, and crevices in the ground below the water table (3) Water occurring in the zone of saturation below the earth's surface
1 Water that flows or seeps downward and saturates soil or rock, supplying springs and wells The upper surface of the saturated zone is called the water table 2 Water stored underground in rock crevices and in the pores of geologic materials that make up the Earth's crust (see surface water)
water found in the pore spaces of bedrock or soil Groundwater reaches the land surface through springs or it can be pumped using wells
- The subsurface water within the zone of saturation This water moves under the influence of gravity and is, in many instances, a source of well water for domestic and agricultural use
Groundwater is water that is found under the ground. Groundwater has usually passed down through the soil and become trapped by rocks. water that is below the ground. or subsurface water Water that occurs below the surface of the Earth, where it occupies spaces in soils or geologic strata. Most groundwater comes from precipitation, which gradually percolates into the Earth. Typically, 10-20% of precipitation eventually enters aquifers. Most groundwater is free of pathogenic organisms, and purification for domestic or industrial use is not necessary. Furthermore, groundwater supplies are not seriously affected by short droughts and are available in many areas that do not have dependable surface water supplies
water beneath the earth's surface that fills the spaces and flows between soil particles and rock Groundwater is what you find in wells and springs Two out of every three Wisconsin citizens drink groundwater
Water found beneath the land surface, in the zone of saturation below the water table
Water abstraction, water extraction, or groundwater abstraction is the process of taking water from any source, either temporarily or permanently. Most water is used for irrigation or treatment to produce drinking water
