Summary

The Mississippi River Valley alluvial aquifer (“alluvial aquifer”) is one of the most extensively developed aquifers in the United States. The alluvial aquifer is present at the land surface in parts of southeastern Missouri, northeastern Louisiana, western Mississippi, western Tennessee and Kentucky near the Mississippi River, and throughout eastern Arkansas. Historical (1940–2006) and recent (2019–20) aquifer-test datasets were compiled to model transmissivity and hydraulic conductivity of the alluvial aquifer from recent (2018–19) airborne electromagnetic (AEM) survey data. This data release contains the aquifer-test and geophysical data along with computer codes written in Matlab version R2014a syntax used to process the data as [...]

Purpose

The datasets contained in this data release were extracted from larger parent datasets to: (1) develop e–h relations between alluvial-aquifer transmissivity and mean resistivity, and (2) assess the accuracy of the e-h relations developed from historical aquifer-test data acquired between 1940 and 2006 by comparing transmissivity and hydraulic conductivity values modeled with the e–h relations to recent slug-test data acquired between 2019 and 2020. The parent datasets were collected to contribute high-resolution information about subsurface geologic structure to inform hydrologic models, water resource infrastructure studies, and local decision making concerning the alluvial aquifer.
