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 area is underlain by the C aquifer and Redwall-Muav aquifer. The C aquifer is a water-table aquifer, with a depth of up to 1500 feet to the water table and is dry in the west, except for perched water-bearing zones. It is underlain by the Redwall-Muav, confined and up to 3200 feet below the land surface.
Riparian habitat covers only 1% of the Southwest but supports 50% of breeding bird species and is vital as a food source for migrating avifauna. [23] Fredlake reasoned that beaver dams would raise the water table, allowing groundwater to recharge the river's flow in the dry season. From 1999 to 2002, 19 beavers were released into the SPRNCA, a ...

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 ...
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.
