[1] Quantifying the spatial configuration of hydraulic conductivity (K) in heterogeneous geological environments is essential for accurate predictions of contaminant transport, but is difficult because of the inherent limitations in resolution and coverage associated with traditional hydrological measurements. To address this issue, we consider crosshole and surface‐based electrical resistivity...

296 A wellfield (Boise Hydrogeophysical Research Site or BHRS) is being developed in Boise, Idaho, for hydrologic and geophysical research in a shallow, coarse (cobble-and-sand), alluvial aquifer. Our goal is to develop cost-effective methods for quantitatively characterizing the distribution of permeability in heterogeneous alluvial aquifers using hydrologic and geophysical techniques. Respons...

In the last decade, time-domain crosshole ground-penetrating radar full-waveform inversion has been applied to several different test sites and improved resolution reconstruction of subsurface properties. The requires diligent executed pre-processing steps guarantee a successful minimize risk being trapped in local minimum. Thereby, one important aspect is starting models inversion. Generally, ...

Mapping high permeability sand occurrences in clayey till is fundamental for protecting the underlying drinking water resources. Crosshole ground penetrating radar (GPR) amplitude data have potential to differentiate between and clay, can provide 2D subsurface models with a decimeter-scale resolution. We develop probabilistic straight-ray-based inversion scheme, where we account forward modelin...

Inversion methods that build on multiple-point statistics tools offer the possibility to obtain model realizations that are not only in agreement with field data, but also with conceptual geological models that are represented by training images. A recent inversion approach based on patch-based geostatistical resimulation using graph cuts outperforms state-of-the-art multiple-point statistics m...
