Characterizing soil erosion potential using electrical resistivity imaging
… characteristics also influence soil in situ bulk electrical resistivity (ER) measurements. The objective of this study was to characterize soil erosion potential by correlating the in situ ER of soil with erodibility measured in the Kansas State University Erosion Function Apparatus (KSU-EFA). ER …

Determining the influence of transpiration on soil moisture pathways using electrical resistivity imaging
… affected by daily transpiration using time-lapse electrical resistivity imaging (ERI) on a ponderosa pine and the surrounding soil during the growing season. By comparing sapflow measurements to the ERI data, we find that high periods of sapflow within the diel cycle are aligned with decreases in …

Time-lapse Geophysical Investigations over Known Archaeological Features Using Electrical Resistivity Imaging and Earth Resistance
Electrical methods of geophysical survey are known to produce results that are hard to predict at different times of the year, and under differing weather conditions. This is a problem which can lead to misinterpretation of archaeological features under investigation. The dynamic relationship …

Using Electrical Resistivity Imaging to Relate Surface Coal Mining Valley Fill Characteristics to Effluent Stream Quality
… such as age and construction method. We used electrical resistivity imaging (ERI) to investigate the subsurface structure of four valley fills in two dimensions. We combined ERI with artificial rainfall to investigate the location and transit time of hydrologic preferential infiltration …

Electrical Resistivity Imaging of Preferenital Flow through Surface Coal Mine Valley Fills with Comparison to Other Land Forms
… in fill material. We tested the effectiveness of electrical resistivity imaging (ERI) to monitor subsurface hydrologic flow paths in valley fills. ERI is a non-invasive geophysical inverse technique that maps spatiotemporal changes in resistivity of the subsurface. When a resistance or conductive …

Identification of surface water and groundwater relationship at Universiti Tun Hussein Onn Malaysia (UTHM) Campus
… demands. The Schlumberger array was used for Electrical Resistivity Imaging (ERI) during data acquisition to identify potential shallow aquifers and suitable locations for boreholes which function as observation wells. Three new boreholes were installed and the ERI results showed that this …

Groundwater-surface water exchange within montane and alpine regions of the Front Range and Rocky Mountains, Colorado
… These tracer tests were paired with time-lapse electrical resistivity and modeled using OTIS to examine how solute transport and storage changed with decreasing stream discharge.
