Late Pleistocene New Jersey Shelf sedimentation as a response to glacio-eustatic sea level rise
(2009-08)
Shallowly-buried channel systems have been imaged on the New Jersey Shelf with high-resolution seismic imaging. These channels formed as riverine systems that occupied the exposed shelf during the Last Glacial Maximum, ...
Radar interferometry measurement of land subsidence in El Paso, Texas
(2004)
This work presents the application of radar interferometry to detect land subsidence associated with water pumping in El Paso, Texas and adjacent areas. Geological and hydrological information are compared with the radar ...
The secondary permeability of "impervious" cover in Austin, Texas
(2007-12)
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 ...
Non-Darcy flow through porous media
(2000)
Since its introduction, Darcy's law has been implemented as a mathematical tool that allows simple calculation and prediction of low velocity subsurface flows. However, turbulence, non-isothermal conditions, as well as ...
Integration of geological and petrophysical data in reservoir characterization of Pennsylvanian Upper Morrow "C-sand" in Wilburton Field, Morton County, Kansas
(2005)
The Morrow C-sand reservoir at Wilburton Field is an incised-valley-fill fluvial sandstone of Pennsylvanian age. It is compartmentalized into five flow units, each of which possesses particular geological and petrophysical ...
Mesoproterozoic structural evolution and lithologic investigation of the western Llano Uplift, Mason County, Central Texas
(2000-05)
The Llano Uplift of central Texas contains the largest exposure of Mesoproterozoic rocks along southern Laurentia and is thus crucial to the understanding of orogenesis and plate reconstructions along a portion of one of ...
Geochemical evolution of ground water in the Barton Springs segment of the Edwards Aquifer
(2005)
The water quality in a karst (limestone) aquifer changes over time, making the application of traditional hydrogeologic principles difficult or impossible. This research's goal was to advance the understanding of the ...
Geochemical and isotopic tracing of Paleozoic groundwater flow in breached anticlines : a case study at Lower Kane Cave, Bighorn Basin, Wyoming
(2004-08-16)
Lower Kane Cave is forming in the upper Mississippian Madison Limestone by sulfuric acid speleogenesis. The cave is located along the axialtrace of the Little Sheep Mountain anticline where the Paleozoic units have been ...
Variable-density groundwater flow beneath the wind-tidal flats of Padre Island
(2007-05)
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 ...
Application of ground-based LIDAR to constrain topographic strike-variability and facies proportions of progradational San Andres Formation clinoforms, Last Chance Canyon, NM
(2007)
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 ...
