Characterisation of sedimentary structure and hydraulic behaviour within the unsaturated zone of the Triassic Sherwood Sandstone aquifer in North East England
… grainsize analysis, logging of nearby outcrops, borehole geophysics and Ground Penetrating Radar (GPR). GPR is ideal for vadose zone hydrogeological applications as the majority of the features imaged are visible to radar as a result of variations in capillary, held moisture, and the amount of …

Aquifer Characterization in the Blue Ridge Physiographic Province
… a variety of array techniques combined with borehole geophysical logs revealed new insights into this geologically complex province. Dipole-dipole arrays were particularly important in gathering high resolution resistivity profiles that document horizontal and vertical resistivity variation …

Evaluating Preferential Recharge in Blue Ridge Aquifer Systems Using Saline Tracers
Multiple saline tracers were used to explore the role of geologic structure on groundwater recharge at the Fractured Rock Research Site in Floyd County, Virginia. Tracer migration was monitored through soil, saprolite, and fractured crystalline bedrock for a period of 3 months with chemical, …

Elastic Properties of Rock Salt: Lab Measurements, Numerical and Physical Modeling, and Gulf of Mexico Well Logs and VSP
… values were studied from 147 log suites from boreholes drilled through rock salt in the northern Gulf of Mexico. Within the salt formations, P-wave velocities increase slightly with depth (around 5 m/s per km). In addition, a set of numerical and physical models were studied for the salt flank …
