Alluvial aquifer
Coastal alluvium and CID aquifers are comparatively similar in terms of hydraulic conductivity and transmissivity; however, the spread in terms of storativity is larger for coastal alluvium aquifers possibly due to the presence of finer and more varied sediments in the depositional environment of the coastal alluvial plains. Valley-fill ...The Mississippi River Alluvial Aquifer (MRAA) in south-central Louisiana is recharged by the Mississippi River, and there are discharge zones to the west and east. Recharge waters from the Mississippi River are fresh, but Cl − levels in the western portions of the aquifer are as high as 1000 mg/L. The aquifer is an important source of water ...

Jun 1, 2012 · The USGS has established a groundwater-level monitoring network in the South Platte alluvial aquifer by instrumenting 20 existing USGS NAWQA wells with pressure transducers and data loggers. Sources/Usage: Public Domain. Land use in the South Platte River Basin varies from forested areas in the mountains, to urban areas along the Front Range ... and aquifer testing: 1. There is a uniform, thick aquifer at the site – There are no intervening clay layers, so the aquifer is not separated into multiple units. The hydraulic conductivity of this aquifer is in the range of 500 ft/ day – which is on the high end for aquifers in Indiana. This finding was also supported by the preliminaryThe thickness of these highly felsic alluvial deposits ranged from 200 feet (ft) near Victorville and near Barstow to a thin veneer about 30 ft thick downstream from Victorville and downstream portions of the floodplain aquifer within the Mojave Valley. Groundwater in the Mojave River and Morongo areas was generally oxic and alkaline (pH≥7.5).Groundwater availability in Bangladesh is governed by its subtropical monsoon climate, aquifer storage capacity, consumption rate along with changes in volume and distribution of groundwater recharge conditions. Groundwater withdrawal from the shallow alluvial aquifer (depth <150 m) is the country’s source of the arsenic-enriched waters.The Brazos River alluvium aquifer underlies the Brazos River in Texas from Bosque County to Fort Bend County. The aquifer, one of 21 minor aquifers in the State, supplies water for irrigation, domestic, stock, and commercial use. The Brazos River alluvium aquifer likely will become more important in the future as demand for water increases ...
Arsenic is a potentially toxic element of concern for environmental compartments, and it is a frequent pollutant in many abandoned industrial sites.

The alluvial stream-aquifer systems are classified based on the predominant regional ground-water flow component as underflow-component dominated, baseflow-component dominated, or mixed. On the basis of the results of this study, we conclude that the dominant regional ground-water flow component, base-flow or underflow, can be …These two aquifers are fed by the waters of the Oum Rbia River (Barakat et al. 2016). The thickness of the Tadla Plain synclinorium aquifers varies widely, implying heterogeneity in the availability of groundwater resource. The thickness of the Mio-Pliocene–Quaternary alluvial aquifer exceeds 80 m over the entire perimeter of Tadla.
Dec 31, 2016 · The Brazos River Alluvium Aquifer is a minor aquifer found along the Brazos River in east-central Texas. The aquifer is as much as 7 miles in width and extends along 350 river miles from southern Bosque County to eastern Fort Bend County.
