We present a 2.5-D forward modeling algorithm for electrical resistivity data. The algorithm
incorporates a boundary condition and source singularity correction that greatly reduces the …

Core Ideas Lateral flow patterns revealed by dye tracing agreed with time‐lapse GPR data.
Lateral flow downslope varied from< 1 to 1 m at adjacent sites. 3D radar detected banding in …

Determining the 3D spatial distribution of subsurface properties is a challenging, but critical,
part of managing the cleanup of contaminated sites. We have developed a minimally …

The spatial distribution of the electrical resistivity data provides useful information for
investigating and modeling the fluid transport processes. 3D electrical resistivity distribution …

Electrical resistivity tomography (ERT) is examined as a method to provide spatially
continuous information about aquifer properties through imaging of tracer flow and transport …

One of the core goals in near surface geophysics is the imaging of fluid flow and the
associated determination of hydrological parameters. While the direct determination of …

Preferential flow (PF), which bypasses large portions of the soil or subsurface matrix, is
critical in the transport of water and dissolved constituents in the unsaturated zone. To test …
