Alluvial aquifer.
Water from the alluvial aquifer is a hard, calcium bicarbonate type containing excessive iron in most places. In 1975, 745 Mgal/d, mostly for irrigation, were withdrawn from the alluvial aquifer. In the 7,000 sq mi area in northwestern Mississippi, the alluvial aquifer has been estimated to be capable of yielding over 1,700 Mgal/d, not ...

Based on the ...Abstract - Water from small alluvial aquifers constitutes an attractive and low-cost option for irrigation and rural development in Northeastern Brazil.The alluvial aquifer consists of permeable sands and gravels that are 20-meters thick and covered by a layer consisting of clay and humus of approximately 1 meter. The depth to groundwater table varies between 1.4 and 1.7 m (Fig. 1d). pH is neutral around 7.2 (De Carvalho Dill et al., 1992).MSR, the main recharge component in arid and semi-arid basins, involves two related processes: mountain front recharge (MFR) and mountain block recharge (MBR). MFR is recharge from stream runoff at mountain fronts to the adjacent alluvial aquifer while MBR is recharge through mountain bedrock (Houston, 2002, Meixner et al., 2016).
The well field is in an alluvial aquifer adjacent to the Cedar River. Parent herbicide concentrations generally were greatest in June, and decreased in July and August. Atrazine was most frequently detected and occurred at the greatest concentrations; acetochlor, cyanazine and metolachlor also were detected, but at lesser concentrations than atrazine.
Sep 15, 2014 · Alluvial aquifers, confined by looser material, are also favorable sources of groundwater rather than the tougher confined aquifers. However, some confined aquifers, if drilled, can contain enough pressure to drive water to the surface without a pump.

The CI aquifer (1 million km 2), one of the largest confined aquifers in the world, shared between Algeria (700.000 km 2), Tunisia (80.000 km 2) and Libya (250.000 km 2), constitutes the main groundwater resource in southern Tunisia.An …The alluvial aquifer is composed of sand and gravel deposits that are present on both sides of the Missouri River. The alluvial aquifer is as much as 100 ft thick at the well field and is overlain by about 20 ft of clay, silt, and sand deposits (Kelly, 1996).This study contributes data from field investigations and observations of a sand river currently utilised for small-scale irrigation. The objectives include …
Rates of groundwater loss often exceed the rate of recharge due to excessive pumping or drought, which causes water levels in aquifers to drop. This disparity between recharge rates and groundwater losses led to water level declines during 2001-2006, ranging from 0.6 to more than 21 feet in many major Oklahoma aquifers, as shown in Figure 1.
An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground..

Ground water infiltrates the alluvial aquifer from the tuffs via springs and subsurface flow. The close proximity of the water table in the alluvium to the ground surface promotes evapotranspiration, and evapotranspiration causes a decrease in the volume of ground water and an increase in chemical concentration. Colinear increases inThe Mississippi River Valley alluvial aquifer (alluvial aquifer) is a water-bearing assemblage of gravels and sands that underlies most of eastern Arkansas and several adjacent States. Ground-water withdrawals have caused cones of depression to develop in the alluvial aquifer water-level surface, some as much as 100 feet deep. Aquifer: One or more strata of rock or sediment that is saturated and sufficiently permeable to yield economically significant quantities of water to wells or springs.
