In arid areas, check dams are often built to increase groundwater recharge in a process called managed aquifer recharge. Winter runoff thus can be stored in aquifers, from which the water can be withdrawn during the dry season for irrigation, livestock watering, and drinking water.
Herman Bouwer (1927–2013) was a hydrological scientist [1] who worked in groundwater hydrology and water resources management, with a specialization in the area of Managed Aquifer Recharge (MAR). He was born in the Netherlands and moved to the United States in 1952 to study for his PhD at Cornell University .
California's groundwater levels rose significantly in 2023, one of the wettest years in decades. State officials say efforts to replenish aquifers helped.
California’s San Joaquin Valley may be sinking nearly an inch per year due to the over-pumping of groundwater supplies, with resource extraction outpacing natural recharge, a new study has found.
In a new report, scientists say the U.S. is facing serious challenges as groundwater is depleted in many areas. They call for a national effort to safeguard aquifers.
Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [ 1 ]
How did USACE reach its conclusion that a manufacturing complex expected to use up to 6.6 million gallons of water per day from four new wells drilled into the Floridan Aquifer would have a ...
