Ground-water flow i the Gulf Coast aquifer systems, south-central United States. by A.K Williamson Download PDF EPUB FB2

The Gulf Coast regional aquifer systems constitute one of the largest, most complicated, and most interdependent aquifer systems in the 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.

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. Ground-water flow in the Gulf Coast aquifer systems, south central United States; a preliminary analysis; ; WRI; ; Williamson, A.

GROUND-WATER PUMP AGE FROM THE GULF COAST AQUIFER SYSTEMS,SOUTH-CENTRAL UNITED STATES by Thomas O. Mesko, Thomas A. Williams, DJ. Ackerman, and Alex K. Williamson ABSTRACT The gulf coast aquifer systems of the south-central United States were divided into 10 model layers for regional analysis of ground-water flow.

The Gulf Coast Aquifer is a major aquifer paralleling the Gulf of Mexico coastline from the Louisiana border to the border of Mexico. It consists of several aquifers, including the Jasper, Evangeline, and Chicot aquifers, which are composed of discontinuous sand, silt, clay, and gravel beds.

Ground‐water flow in the Floridan aquifer system and the Tertiary sand aquifer prior to development is generally perpendicular to the coast. Predevelopment flow in the Cretaceous aquifers, however, turns northeastward as it approaches the coast, almost paralleling the coast.

The change in flow direction is caused by less effective intervening. Get this from a library. Ground-water pumpage from the Gulf Coast aquifer systems,south-central United States. [Thomas O Mesko; Geological Survey (U.S.);].

A multiple-regression methodology was used to help answer questions concerning model reliability, and to calibrate a time-dependent variable-density ground-water flow model of the gulf coast aquifer systems in the south-central United States.

More than 40 regression models with 2 to 31 regressions parameters are used and detailed results are presented for 12 of the models.

THE GULF COAST AQUIFER SYSTEMS, SOUTH-CENTRAL UNITED STATES By Terry A. Wilson and R.L. Hosman ABSTRACT As part of the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) program, the Gulf Coast RASA was begun to investigate ground-water flow systems in the Coastal Plain of the south-central United States.

A complex, multilayered ground-water flow system exists in the Coastal Plain sediments of Texas. The Tertiary and Quaternary clastic deposits have an areal extent ofsquare miles onshore and in the Gulf of Mexico. Two distinct aquifer systems are recognized within the sediments, which range in thickness from a few feet to more t feet The older system--the Texas coastal.

The Mississippi Embayment aquifer system is composed of six regional aquifers covering aboutsquare 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 and Claiborne groups.

Water‐table altitude, a controlling factor for ground‐ water flow, was estimated from detailed topographic data by subtracting the estimated depth‐to‐water. Land‐surface altitude of the Coastal Plain in the south‐central United States varies from 0 to more than feet above sea level.

[Robert A Pettijohn; Geological Survey (U.S.),]. It shows an unconfined aquifer extending seaward and a watertable merging with the shoreline. Sea water enters the aquifer and because it has higher density it extends landward beneath the freshwater lens. Confined aquifers also extend seaward.

In both aquifer types, the degree to which sea water enters the aquifers largely depends on the overall energy, or hydraulic drive of groundwater flow.

Geological Survey HA ). In cooperation with Air Force Civil Engineer Center (AFCEC), the U.S. Geological Survey (USGS) is evaluating the hydrogeology of the Air Force Research Laboratory (AFRL) and Site 25 areas of Edwards Air Force Base (EAFB) and the adjacent North-Muroc groundwater subbasin to help determine regional groundwater movement and the possible long-term movement and pathways of contaminated.

This Ground Water Atlas of the United States is a series of USGS publications that describe the location, the extent, and the geologic and hydrologic characteristics of the important aquifers of the Nation.

The US Geological Survey in cooperation with the Harris-Galveston Coastal Subsidence District, the Fort Bend Subsidence District, and the Lone Star Groundwater Conservation District has updated the model for the northern portion of the Gulf Coast Aquifer System. The Floridan Aquifer System is the portion of a principal artesian aquifer that extends across several states.

The principal artesian aquifer is the largest, oldest and deepest aquifer in the southeastern U.S. Ranging acrosssquare miles, it underlies all of Florida and parts of southern Alabama, southeastern Georgia and southern South. aquifer in the same manner that ground water moves.

(Some contaminants, because of their phys-ical or chemical properties, do not always follow ground water flow.) It is possible to predict, to some degree, the transport within an aquifer of those substances that move along with ground water flow.

For example, both water and certain. A numerical model of variable-density groundwater flow and miscible salt transport is developed to investigate the extent of seawater intrusion in the Gulf coast aquifers of Alabama, USA. The Floridan aquifer system, composed of the Upper and Lower Floridan aquifers, is a sequence of Paleogene carbonate rock which spans an area of aboutsquare miles (, km 2) in the southeastern United underlies the entire state of Florida and parts of Alabama, Georgia, Mississippi, and South Carolina.

The Floridan aquifer system is one of the world's most productive. This aquifer is one of the most productive in the United States and a major source of water in the region. Duringabout million gallons per day (Mgal/d) were withdrawn from the Upper and Lower Floridan aquifers in Georgia, primarily for irrigation, industrial, and public-supply uses (Painter, ).
