In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
The tribes alleged that the pumping of water by Peabody Energy caused a severe decline in the number of springs and reduced their access to potable water. [4] Both tribes, situated in an arid semi-desert, attach religious significance to water, consider it sacred, and have cultural, religious, and practical objections to over-use of water.

Arizona, Nevada and Mexico will continue to live with less water next year from the Colorado River after the U.S. government on Thursday announced water cuts that preserve the status quo. The ...
Cross section showing the water table varying with surface topography as well as a perched water table Cross-section of a hillslope depicting the vadose zone, capillary fringe, water table, and the phreatic or saturated zone. (Source: United States Geological Survey.) The water table is the upper surface of the zone of saturation.
The flora includes Fremont cottonwood (Populus fremontii), Goodding willow (Salix gooddingii), velvet mesquite trees, and the Huachuca water umbel (Lilaeopsis schaffneriana spp. recurva), Federally listed as endangered. [5] In recent decades, rapid growth and population increases in southern Arizona has caused concern with this river.
In summary, as long as at least 7,500,000 acre-feet (9.3 km 3) of water is available from the Colorado River, California is allocated 4,400,000 acre⋅ft (5.4 km 3); Nevada, 300,000 acre⋅ft (0.37 km 3); and Arizona, the remainder. If more water is available, California is entitled to 50% of the water from the Colorado River, Arizona to 46% ...
