Simulated response of the Sparta Aquifer to outcrop area recharge augmentation, southeastern Arkansas

Abstract

the aquifer without the existence of any permeability barriers between the canals and the aquifer.

Potentiometric surfaces (2013, 2015), groundwater quality (2010–15), and water-level changes (2011–13, 2013–15) in the Sparta-Memphis aquifer in Arkansas

“…Because the Sparta-Memphis aquifer is confined across most of Arkansas, it has only a fraction of the water storage of the MRVA aquifer. For this reason, water managers have expressed great concern regarding the sustainability of agricultural withdrawals from the Sparta-Memphis aquifer (Hays, 2001;McKee and Hays, 2002). Kresse and others (2014) reported that more water was used from the Sparta-Memphis aquifer for irrigation in Arkansas than for any other purpose as of 2010.…”
