Example data from MoisturEC: a new R program for moisture content estimation from electrical conductivity data
This dataset includes example data used for demonstration of the moisturEC program. This includes inverted electrical resistivity data, model resolution from the inversion, point moisture information, and conductivity-saturation calibration information. The data are from a field site in Coventry, CT outfitted with five, Decagon 5TE moisture probes, arranged along a 28 m transect at different...
Wetland-scale mapping of preferential fresh groundwater discharge to the Colorado River
Quantitative evaluation of groundwater/surface water exchange dynamics is universally challenging in large river systems, because existing methodology often does not yield spatially‐distributed data and is difficult to apply in deeper water. Here we apply a combined near‐surface geophysical and direct groundwater chemical toolkit to refine fresh...
Briggs, Martin A.; Nelson, Nora; Gardner, Philip M.; Solomon, D. Kip; Terry, Neil; Lane, John W. MoisturEC: a new R program for moisture content estimation from electrical conductivity data
Noninvasive geophysical estimation of soil moisture has potential to improve understanding of flow in the unsaturated zone for problems involving agricultural management, aquifer recharge, and optimization of landfill design and operations. In principle, several geophysical techniques (e.g., electrical resistivity, electromagnetic induction, and...
Terry, Neil; Day-Lewis, Frederick D.; Werkema, Dale D.; Lane, John W. Scenario Evaluator for Electrical Resistivity survey pre-modeling tool
Geophysical tools have much to offer users in environmental, water resource, and geotechnical fields; however, techniques such as electrical resistivity imaging (ERI) are often oversold and/or overinterpreted due to a lack of understanding of the limitations of the techniques, such as the appropriate depth intervals or resolution of the methods....

Scenario Evaluator for Electrical Resistivity (SEER) Survey Pre-Modeling Tool
The USGS Scenario Evaluator for Electrical Resistivity (SEER) is a quick and simple Excel-based decision support tool practitioners can use to assess the likely outcome of using two-dimensional (2D) electrical resistivity imaging for site characterization and remediation monitoring.
