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 ...
Rural Arizona needs the power to manage our own groundwater, county supervisors say, not let those with the deepest wells pump everyone else dry. Rural Arizona is facing a water crisis. Yet for 3 ...

A study in an arid agricultural region of Arizona [3] showed that, even with a water level recovery of 100 ft after groundwater pumping was stopped, the land surface continued to subside for decades. This is a result of the continued dewatering of aquitards (fine-grain layers that slow the movement of groundwater) from stresses mentioned in the ...
Plans to develop the desert west of Phoenix outstrip the water available to the area, a newly released report from Arizona’s Department of Water Resources shows. Arizona Gov. Katie Hobbs (D) on ...
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.
In most areas the plan was to reduce the water table to 4 to 6 feet (1.2 to 1.8 m). Irrigation water would be provided for 128,787 acres (52,118 ha) of arable land. 18% of the land was Indian land, which caused some concern over whether Indian rights were being sufficiently protected, but the plan was finally approved by the president on 13 ...
Three years later, the Bureau of Reclamation and the State of Arizona agreed on an alternative to Orme. This was known as Plan 6, and it recommended four projects: a reconstruction of the Stewart Mountain Dam , a new or larger Roosevelt Dam , the Cliff Dam on the Verde River and finally, the New Waddell Dam on the Agua Fria River (a tributary ...
