(redirected from Groundwater aquifer)Also found in: Thesaurus, Medical, Encyclopedia. Related to Groundwater aquifer: groundwater rechargeaq·ui·fer (ăk′wə-fər, ä′kwə-) n. An underground layer of permeable rock, sediment, or soil that yields water. Aquifers can range from a...
The Guadalquivir alluvial aquifer near Andújar has been studied and modeled since 1988. The original period of water balance has been extended from 1988 to 2007. Early versions of the water balance model provided too large recharge estimates that had to be scaled down to reproduce measured ground...
aquifer systems. These findings imply that groundwater pumping can draw mobile surface-borne pollutants to deeper depths than they would reach in the absence of pumping. We conclude that intensive groundwater pumping can draw recently recharged groundwater deeper into aquifer systems, potentially ...
Ground water atrazine concentrations at the site decreased from 2 to 0.2 mg L-1 due to recharge. Both NO3-N and atrazine contamination dramatically improved from concentrations ex 展开 关键词: artificial recharge ground water quality aquifer storage recovery nitrate contamination infiltration ...
During the last few decades, the Grombalia shallow, an unconfined aquifer, had been under stress by groundwater pumping due to the increasing population and development of agricultural activity. Recently, the aquifer has displayed an important decline in the water level of boreholes and wells, an...
The groundwater pollution risk in the semi-confined aquifer was lower than that in the phreatic aquifer. The groundwater pollution risk mapping provides a valuable scientific reference for the groundwater pollution prevention and control with the focus on the "pollution source" and "groundwater ...
The Hajar Super Group is the most important carbonate rock aquifer of northern Oman’s Mountains. The carbonate rocks are highly fractured with karstic topography, allowing groundwater to be stored, migrate over long distances and emerge at the surface via many different springs along the boundary ...
On the other hand, it is still not possible to calculate closed balances for the groundwater and surface water bodies involved. Usually, neither entire gauged surface water catchments nor the whole extent of the groundwater aquifer in question can be studied at this scale. Thus, processes that...
A lot of hydraulic conductivity data regarded as regionalized variable has been obtained by aquifer test. The variograms fitted with spherical model are calculated in parallel and perpendicular groundwater flow directions; the correlation length in parallel groundwater flow is twice longer than in ...
