Leveraging Big Data to Preserve the Mississippi River Valley Alluvial Aquifer: A Blueprint for the National Center for Alluvial Aquifer Research

open access: yesLand, 2022
The challenge of a depleting Mississippi River Valley Alluvial Aquifer (MRVAA) requires reducing groundwater withdrawal for irrigation, increasing aquifer recharge, and protecting water quality for sustainable water use.

Perceptions of Irrigation Water Management Practices in the Mississippi Delta

open access: yesAgronomy, 2022
The Mississippi River Valley Alluvial Aquifer (MRVAA) is being depleted, and practices that improve water stewardship have been developed to reduce drawdown. This study assesses how Mississippi Delta producers changed their perceptions of these practices

Cover crops and landscape positions mediate corn–soybean production

open access: yesAgrosystems, Geosciences & Environment, 2022
Ecosystem services and cash crop benefits provided by cover crops (CCs) can be affected by temporal and spatial variability of CC performances as influenced by topographic position of the field. A watershed‐scale study was initiated in 2015 to assess the

A Quantitative Review of Irrigation Development in the Yazoo–Mississippi Delta from 1991 to 2020

open access: yesAgronomy, 2021
The Yazoo–Mississippi Delta is one of the regions within the Lower Mississippi River Basin where substantial irrigation development and consequent groundwater depletion have occurred over the past three decades. To describe this irrigation development, a

2D Electrical Resistivity Imaging to delineate the exact boundary and true thickness of granular aquifers

open access: yesTikrit Journal of Pure Science, 2023
Electrical resistivity imaging (ERI) is one of the best geophysical techniques for studying subsurface and groundwater aquifer investigations. In clastic sediments, determining the exact boundary between different layers on the inverse section of ERI is
