We use complex conductivity measurements to predict the hydraulic conductivity (K) of
unconsolidated materials. The samples include natural sediments and artificial sand/clay
mixtures. We apply the Börner et al.[1996] model, which is based on the Kozeny‐Carman
equation and incorporates electrical estimates of formation factor (F) and specific surface
area per unit volume‐to‐porosity ratio (Spor), from the real (σ′) and imaginary (σ ″)
conductivity components respectively. We find that K correlates with σ ″but shows no …

Mechanistic models now exist to predict hydraulic conductivity (K) from the spectral‐induced
polarization (SIP) response of granular media. We examined the predictions of such a model
on unconsolidated coarse fluvial sediments and compared them to those obtained with a
modified Kozeny‐Carman (KC) model. Samples were retrieved from the Boise
Hydrogeophysical Research Site (BHRS), located on a gravel bar adjacent to the Boise
River, Idaho. A sample holder (0.102 m diameter and 0.12 m in length) was designed to …
