In Mississippi, the Smackover Limestone covered over earlier evaporite deposits. A complex stratigraphic sequence formed during the Cretaceous , with the reef limestones, anhydrite and sandstones of the Rodessa Formation, Mooringsport Formation, Paluxy Formation, Gordo Formation and Coker Formation, overlain by the Eutaw Group, Austin Chalk ...
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

Groundwater use in 1980 for public supply averaged 121 million gallons per day, serving over 700,000 people in southern Louisiana. In southwestern Mississippi, where the aquifer system is also a major source of water, utilization for these categories in 1980 totaled million gallons per day, serving about 270,000 people.
Examining the composition of stable isotopes in the water found in soil, rivers, groundwater, and xylem (or vein systems) of vegetation, using mass spectroscopy, which measures and sort the masses in a sample, along with data on the changes in groundwater depth coupled with the time and vegetative rooting patterns, shows spatial changes over time in the use of groundwater by the vegetation in ...
The Mississippi Headwaters subregion, sometimes called the Mississippi Headwaters Hydrologic Subregion, is a second-level subdivision [1] covering approximately 20,200 sq mi (52,000 km 2) and includes the Mississippi River basin above the confluence with the St. Croix River basin, excluding the Minnesota River basin.

In 2008, data covering 66,200,000 acres (268,000 km 2) were added to the Wetlands Geodatabase. These included 28,100,000 acres (114,000 km 2) of updated wetland map information, new data for 6,800,000 acres (28,000 km 2) not previously available and 31,300,000 acres (127,000 km 2) of data that were captured in digital format. An additional ...
The Pascagoula River is a river, about 80 miles (130 km) long, in southeastern Mississippi in the United States. [1] The river drains an area of about 8,800 square miles (23,000 km²) and flows into Mississippi Sound of the Gulf of Mexico. The Pascagoula River Basin is managed by the Pat Harrison Waterway District. [2]
The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources.
