The term "impervious" is commonly used in urban settings to describe the permeability of buildings, roads, and parking lots. When estimating recharge to an aquifer underlying an urbanized area, impervious cover becomes a ...

Field evidence for density-driven free convection, a potentially important groundwater transport process, has been examined at Padre Island National Seashore to determine if this phenomenon can develop under natural ...

Progradational mixed-carbonate/siliciclastic San Andres Formation clinoforms at Last Chance Canyon, New Mexico were quantitatively mapped and modeled using techniques developed for use with LIDAR (Light Dectection and ...

The Nacimiento Block is located in the Southern Coast Ranges of California, and consists mainly of Franciscan Complex accretionary prism rocks. It is cross-cut by the San Gregorio-Hosgri Fault Zone, a major right-lateral ...

Effective and accurate characterization of fracture populations is a key for hydrocarbon reservoir assessments. The challenge is that fractures in the subsurface are exceedingly difficult to sample in meaningful ways. ...

Seismic inversion is a geophysical tool that uses geologically constrained physical models to infer elastic interval properties (e.g., P-velocity, S-velocity, and density) from seismic interface data (e.g., reflection ...
