Groundwater Resources. Groundwater is the water found beneath the Earth’s surface and occupies the very small cracks and spaces between rocks, gravel and sand. It is a common misconception that groundwater is in the form of underground lakes, streams and rivers, when in reality, groundwater is found inside rocks: in the small pore spaces ...The water supply for the city of Wichita, south-central Kansas, currently comes from the Equus Beds aquifer and Cheney Reservoir. Because these sources are not expected to meet projected city water needs into the 21st century (Warren and others, 1995), artificial recharge of the Equus Beds aquifer was investigated as one alternative to meet future water-supply demands.Brian Frederic Platt. Stephen T. Hasiotis. Daniel R. Hirmas. The purpose of this paper is to test the application of a new, low-cost ($2995.00 US), multistripe laser triangulation (MLT) scanner ...The Kansas Geological Survey's High Plains Aquifer Interactive Atlas provides a large amount of information on the High Plains Aquifer underneath western and central Kansas, which provides 70-80% of the water used in Kansas. Features of this interactive map include: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 series consists of 13 chapters that describe the regional groundwater resources that collectively cover 50 States, Puerto Rico, and the …Interactive Atlas. Use our interactive atlas to view water levels, saturated thickness, and more. This atlas has been created to serve as the primary gateway to the most recent graphical data available for the High Plains aquifer in Kansas. As newer/updated data become available, this atlas will be updated.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. Abstract. The slug test is the most widely used technique for the in situ estimation of hydraulic conductivityin confined and unconfined formations. Currently, there are no generally accepted methods in thegroundwater literature for the analysis of response data from slug tests performed in wells screenedacross the watertable.In all, the Ogallala Aquifer provides 70-80% of water used by Kansans each day. So how much is all that water worth? A recent study from Kansas State University says the aquifer under western Kansas …Mar 19, 2020 · The average groundwater level in 2019 was just 0.7 feet below the 1996 level, and measurements in some intervening years exceeded both years' levels. The Great Bend Prairie aquifer underlies Stafford and Pratt counties and parts of Barton, Pawnee, Edwards, Kiowa, Reno, and Rice counties. Equus Beds GMD 2, a major source of water for Wichita ...

Ministry of Water ...The Equus Beds aquifer in south-central Kansas is a primary water source for the city of Wichita. The Equus Beds aquifer storage and recovery (ASR) project was developed to help the city of Wichita meet increasing current and future demands. The Equus Beds ASR project is a recent part of an 80-year cooperative water science effort …٠١‏/٠٥‏/٢٠٢٠ ... Mobile drip irrigation Our study combines location-specific data on irrigated water withdra Oct 16, 2019 · When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water ( recharge) into the porous rock of the aquifer. The rate of recharge is not the same for all aquifers, though, and that must be considered when ... The Ogallala Aquifer is a vast underground aquifer that underlies the areas of eight states in the United States: South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico and Texas. Both the thickest and the most expansive parts of this aquifer lie in Nebraska. It’s one of the most productive sources of groundwater for ... Furthermore, the lake's residue's esti We propose that the mechanisms driving hyporheic exchange vary systematically with different channel morphologies and associated fluvial processes that occur in mountain basins, providing a framework for examining physical controls on hyporheic environments and their spatial variation across the landscape. shallow-aquifer subsystem to discharge into Ea

The High Plains aquifer underlies an area of about 174,000 square miles that extends through parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The aquifer is the principal source of water in one of the major agricultural areas of the United States.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.The High Plains aquifer is a regional system composed of several aquifers, including the well-known Ogallala aquifer, the Great Bend Prairie aquifer in central Kansas, and the Equus Beds aquifer that provides water for Wichita and surrounding area.In mid-December, the Kansas Water Authority voted to recommend to the governor and 2023 Legislature that Kansas abandon a philosophy of "planned depletion" of the Ogallala Aquifer. The massive underground water reservoir has propelled irrigation of crops for three-quarters of a century.fined alluvium aquifer model, based on datasets from the High Plains aquifer, a series of sorption reactions to goethite, and kaolinite, illite, and montmorillonite were applied. The adjustable parameters include the volume percent of each phase and the cation exchange capacity for the clay minerals (Swedlund et al.,

Jun 16, 2016 · The water supply for the city of Wichita, south-central Kansas, currently comes from the Equus Beds aquifer and Cheney Reservoir. Because these sources are not expected to meet projected city water needs into the 21st century (Warren and others, 1995), artificial recharge of the Equus Beds aquifer was investigated as one alternative to meet future water-supply demands. Over the last century, the names of Kansas aquifers have changed as our understanding of ground-water flow systems has improved. Unfortunately, the current assem-blage of names for aquifer and confining units in Kansas is a mix of the older and the more recent nomenclature (fig. 1). These names derived from local to multistate regionalDec 15, 2022 · This map from the Kansas Geological Survey shows how much the aquifer has declined across western Kansas.
