Ground Water Whirls

Groundwater, 2004
AbstractNumerical experiments with steady‐state ground water flow models show that spiraling flow lines occur in layered aquifers that have different anisotropic horizontal hydraulic conductivities in adjacent layers. Bundles of such flow lines turning in the same direction can be referred to as ground water whirls.

Biodiversity in ground waters

Trends in Ecology & Evolution, 1993
Despite the importance of ground waters in the global water cycle, their ecology and biodiversity have only recently received attention. Three areas are currently being studied: (I ) the origin and colonization ground ground waters, (2) the adaptation of animals to the subterranean environment, and (3) the role of ecotone between surface and ground ...

Fluoride in ground water

Social Science & Medicine. Part D: Medical Geography, 1980
Abstract Water from 72 domestic wells in northeast Ohio was examined to determine the nature and extent of variation in fluoride content. The sedimentary terrain of about 230km 2 includes aquifers characterized as unconsolidated sediments, shales, and sandstones.

International Journal of Mine Water, 1983
In certain circumstances, ground-water causes geotechnical problems and can be considered a nuisance rather than a blessing. The cases where ground-water creates considerable complications include construction, tunneling, mining, landslides, and land subsidence.

Ground Water Recharge

Journal AWWA, 1952
underground reservoirs continuously exceeds the supply, depletion of remaining supplies in storage makes use of an asset which will not be replaced. Some areas, particularly in the Southwest, have discovered the shortage in their ground water account by nearly exhausting it; other areas have found it so concentrated with pollutants that further use is ...
