The Mississippi Embayment aquifer system is composed of six regional aquifers covering about , square miles in parts of Alabama, Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, and Tennessee. The flow analysis presented in this report as part of the Gulf Coast Regional Aquifer-System Analysis study pertains to five aquifers in sediments of the Wilcox . The maximum total sand thickness for the Gulf Coast Aquifer ranges from feet in the south to 1, feet in the north. Water quality varies with depth and locality, but is generally good in the central and northeast-ern parts of the aquifer and declines to the south where the productivity of the aquifer decreases.

Dodson Report Chapter 18 - Assessment of Shallow Recharge and Groundwater-Surface Water Interactions for the LSWP Study Region, Central Texas Coast by. The Gulf Coast Aquifer is a coastal aquifer stretching all along the Gulf Coast, from Florida through Texas and into Mexico. It lies below the southern portions of Mississippi, Alabama, and Georgia, along with over half the states of Louisiana and Florida. The Gulf Coast Aquifer is over miles wide in most sections.

(who was teamed with Intera, Inc., Parsons Engineering Science, Inc., and several individual experts) to develop a model of the central part of the Gulf Coast Aquifer in . As part of the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) program, the Gulf Coast RASA was initiated to investigate all Tertiary and Quaternary aquifers underlying the Coastal Plain in the south-central United States.

Ground-water flow in a ,square-mile area of the south-central United States was modeled for the effect of withdrawing freshwater at the rate of nearly 10 billion gallons per day in from regional aquifers in the Mississippi Embayment, the Texas coastal uplands, and the coastal lowlands aquifer systems.
A major objective of the Gulf Coast Regional Aquifer-System Analysis is to use digital models of regional groundwater flow systems to develop better understanding and to improve management of the resource. Modeling is used to synthesize information about the aquifer systems and to test hypotheses about the relative importance of the components of the systems.

An aquifer can be compared to a bank account, and ground water occurring in an aquifer is analogous to the money in the account. Hydrologists refer to this type of accounting as a water budget.
Ground water can be recharged (deposited) by infiltration from precipitation, surface water. The Southeastern Coastal Plain aquifer system underlies an area of more thansquare miles in Kentucky, Tennessee, Mississippi, Alabama, Georgia, Florida and South Carolina.
The aquifer system ranks 15th in the nation as a source of groundwater for public supply, with about million gallons per day pumped for this and other uses in rows Texas Water. Development Board.

In the simulation model, hydraulic conductivities are separated into two groups: coarse-grained sediments (sands) and fine-grained sediments (silts and clays).Cited by: 6. The objectives of revitalizing and updating the NC-SC RASA models are to improve our understanding of the Atlantic Coastal Plain aquifer system flow paths and recharge; and to evaluate groundwater and surface-water interactions and the potential for reduction in both stream base flow and discharge to wetlands and estuaries as a result of increased groundwater.
As a part of the Texas Water Development Board Ground-Water Availability Modeling program, the U.S. Geological Survey developed and tested a numerical finite-difference (MODFLOW) model to simulate ground-water flow and land-surface subsidence in the northern part of the Gulf Coast aquifer system.AQUIFERS AND QUALITY OF GROUND WATER ALONG THE GULF COAST OF WESTERN FLORIDA By Jack T.
