Waterborne Resistivity Inverted Models, Mississippi Alluvial Plain, 2016-2018

October 9, 2019

This data release consists of two .csv files of inverted models of electrical resistivity created from the processed resistivity data in the accompanying two data releases: (Miller and Others, 2018) and (2018 Raw and Processed, in progress). During 2016, 17, and 18, the U.S. Geological Survey conducted continuous resistivity profiling along 15 rivers or lakes in the Mississippi Alluvial Plain of Mississippi, Arkansas, Louisiana, and Missouri to characterize streambed hydraulic conductivity values. These techniques characterize the near surface geomorphology of the streambed that controls the recharge to the alluvial aquifer. These data can be used to map changes in the lithology of the streambed and identify areas of groundwater-surface water interaction. A total of 2,017 kilometers (km) of continuous resistivity profiles were collected. Individual lengths of surveyed profiles per river include: 203 km on the Yazoo River, 197 km on the Floodway, 270 km on the Sunflower River, 317 km on the Black River, 83 km on the Bogue Phalia, 116 km on the Tallahatchie River, 95 km on the Quiver River, 37 km on the Yalobusha River, 448 km on the White River, 75 km on the Cache River, 42 km on the St. Francis River, 80 km on Eutah Bend, 25 km on Roebuck Lake, 9 km on Sky Lake, and 20 km on a U.S. Department of Agriculture On Farm Storage reservoir. Two data sets are presented in this data release: MAP_CRP_2016_2018_INV_MDLS_FULL.csv contains the entire 15-layer model output from the inversion software and MAP_CRP_2016_2018_INV_MDLS_DOI.csv is a dataset that has been created for studying groundwater-surface water interaction. The data have been post-processed after inversion to accurately reflect the depth of investigation of the instrument and to remove known modeling artifacts. Additionally, the water column, �RHO_DOI_1�, has been removed so only data below the bottom of the streambed is represented.
