Alluvial deposits and terraces in the Nueces River floodplain act as a floodplain conveyance system in combination with river flow and shallow groundwater. The floodplain is underlain by Glen Rose Limestone, which is part of the Trinity Aquifer and also a contributor to Edwards Aquifer recharge, called interformational flow. The Missouri River alluvium is thickest and most used in Kansas near its junction with the Kansas River valley at Kansas City. Alluvial aquifers in other river valleys in Kansas such as the Smoky Hill, Solomon, Saline, Neosho, Marais des Cygnes, and Verdigris also are locally important sources of ground water.Apr 25, 2023 · Approximately 44.2% of the current alluvial aquifer withdrawal of 7.63 billion gallons per day and about 55% of the Sparta aquifer withdrawal of 160 million gallons per day would be sustainable ... Lotikipi and Lodwar aquifers Alluvial sands and sediments, which range up to 80 m deep.

The Trinity-Edwards Aquifer system is the dominant aquifer in Travis County. The updip Trinity Aquifer west of the Balcones Escarpment is generally fresh water while the downdip Trinity Aquifer is saline. The downdip and artesian portion of the Edwards Aquifer provides fresh water eastward until a “bad water ...

However, where water-level declines in the alluvial aquifer are causing decreased well yields, the Sparta aquifer is increasingly used to supplement supplies needed for crop irrigation. In 2000, approximately 85 percent of total ground-water use in Arkansas County came from the alluvial aquifer with the remaining 15 percent from the Sparta aquifer.
