Groundwater-filled body of poorly permeable formations, through which still significant volumes of groundwater may move, although at low flow rates. (un-igrac.org)
Groundwater-filled bodies of poorly permeable formations, through which no or almost no flow of groundwater passes. (un-igrac.org)

In addition, preliminary data indicate identical migration pathways for deep groundwaters and hydrocarbons. (unileoben.ac.at)

1. Prof. Dr. Huenges, how does the potential for harnessing geothermal energy differ between Germany and a country like New Zealand, where completely different natural conditions prevail? (eskp.de)

The basin-anticline outcropping type groundwater is similar to that of the basin type but also has the characteristics of the outcropping type because of the anticlines. (iwaponline.com)

It is planned to take about 60 samples from different stratigraphic horizons in petroleum, geothermal and water supply wells. (unileoben.ac.at)
Results help evaluate the aquifers tapped by water supply wells and are available on the Division of Water Rights web page . (utah.gov)

Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. (wikipedia.org)
In some parts of the state, agricultural operations have pumped so much groundwater that the land is starting to sink . (nakedcapitalism.com)
Governor Brown's executive order has been criticized for not including restrictions on groundwater pumping by agricultural operations, but Brown defended the decision, saying that hundreds of thousands of acres of land were already lying fallow because of the state's water crisis. (nakedcapitalism.com)
It dictates the pace of settlement and agricultural and industrial development of any society and even in recent time, establishment of any human settlement is usually centered on available source of water supply and in modern time, issue of water has equally taken prominences in global matters [1]. (scirp.org)

Always use an experienced and licensed geologist and hydrogeologist, as well as experienced drilling contractors on the design team. (phcppros.com)
Therefore, a common task of the hydrogeologist is determining aquifer properties using aquifer tests. (agnesschildorfer.com)
People need water to live - and to manage water, you need to understand it," said Beatrice Ketchemen Tandia, Head of the Cooperation Division at the Department of National Sciences of the University of Douala in Cameroon, who has participated in IAEA research projects as a hydrogeologist since the early 1990s. (iaea.org)

The mathematical relationships used to describe the flow of water through porous media are Darcy's law, the diffusion and Laplace equations, which have applications in many diverse fields. (agnesschildorfer.com)

In basement provinces groundwater occurrence depend exclusively on discontinuities like fractures, joints, fissures, and weathered litho - zones. (projectclue.com)

Groundwater can be thought of in the same terms as surface water: inputs, outputs and storage. (wikipedia.org)
Due to its slow rate of turnover, groundwater storage is generally much larger (in volume) compared to inputs than it is for surface water. (wikipedia.org)
Wells are drilled to a depth of 3-5 km below the surface to find heat-producing granites. (cleanenergycouncil.org.au)
This extremely hot water is then pushed back to the surface, where the heat is used to drive a turbine and produce electricity. (cleanenergycouncil.org.au)
This especially includes deep geothermal sources, since tapping them requires only a point source - a borehole - so the amount of surface area required is very small. (eskp.de)
The "pump and dump" name implies that water is pumped from an aquifer, then dumped to another location, such as surface water or a storm sewer. (phcppros.com)
We partner with the Utah's Watershed Restoration Initiative, the Utah State University Extension's Community-Based Conservation Program, and Federal and State land and water managers to evaluate changes in groundwater, surface water, wet meadows, and upland vegetation that result from large-scale pinyon-juniper treatment and beaver dam analog projects. (utah.gov)
Water covers over 70% of the earth surface and is undoubtedly the most precious natural resource that exists on the earth. (scirp.org)
2.5% of the world's freshwater, surface water and groundwater have 0.4% and 30.1% representations respectively [2]. (scirp.org)
Geothermal energy is produced from heat stored in the earth originating from when the Earth was formed, from radioactive decay of minerals and from solar energy absorbed at the surface. (groundwateruk.org)
Geothermal energy involves pumping this water to the surface and converting it into energy. (vb.nl)
By drilling into the ground, hot water can be pumped to the surface and converted into energy. (vb.nl)
Close to the surface, the aquifer has an advantage: it can be directly refilled by rainwater. (brgm.fr)
Geological term, indicating an origin related to terrestrial flowing surface water. (un-igrac.org)
