Hydrogeology and preliminary assessment of regional flow in the upper Cretaceous and adjacent aquifers in the northern Mississippi embayment

Updated estimates of water budget components for the Mississippi Embayment Region using a soil-water-balance model, 2000–2020

“…Pumping from this aquifer and underlying aquifers supplies water for the irrigation of crops, aquaculture, drinking water for urban areas, industrial supply, and other uses (Clark and others, 2011;Lovelace and others, 2020). The heavy use of this aquifer has caused substantial groundwater level declines in the alluvial plain of Arkansas and Mississippi, which has motivated a large number of hydrologic studies by the USGS aimed at understanding groundwater movement in the system of aquifers in the area and the potential effect of increasing or reducing pumping on groundwater supply and availability (Boswell and others, 1968;Cushing and others, 1970;Broom and Reed, 1973;Brahana and Mesko, 1988;Ackerman, 1989Ackerman, , 1996Mahon and Ludwig, 1990;Sumner and Wasson, 1990;Arthur and Taylor, 1998;Arthur, 2001;Brahana and Broshears, 2001;Mahon and Poynter, 1993;McKee and Clark, 2003;Reed, 2003;Stanton and Clark, 2003;Kresse and Clark, 2008;Clark and Hart, 2009;others, 2011, 2013).…”
