Non-equilibrium thermodynamic treatment of transport processes in ground-water flow
(University of Nevada, Reno, 1975)
The theory of non-equilibrium thermodynamics is postulated to be applicable to a continuum model of porous medium in which fluxes and forces at points in the fluid phase are averaged over a representative elementary volume.
Determination of timing of recharge for geothermal fluids in the Great Basin using environmental isotopes and paleoclimate indicators
(University of Nevada, Reno, 1990)
Research indicates that the fluid source for geothermal system recharge in the Great Basin is paleorecharge.
A carbon-14 calibrated discrete-state compartment model of the groundwater flow system, Yucca Mountain and vicinity, Nevada-California
(University of Nevada, Reno, 1991)
A carbon-14 calibrated discrete-state compartment model simulates the regional groundwater flow system in southern Nevada yielding estimates of long term average annual recharge volumes, groundwater ages, volumetric flow, ...
Some aspects of the hydrogeology of the Spring Mountains and Pahrump Valley, Nevada, and environs, as determined by spring evaluation
(University of Nevada, Reno, 1966)
The hydrogeology of the Spring Mountains and Pahrump Valley, Nevada has been evaluated. Analysis of geology indicates that nearly all springs are controlled by impermeable fault contacts or exposure of cavernous systems.
Hydrogeologic study of groundwater-surface water interactions at Topaz Lake, Nevada
(University of Nevada, Reno, 1981)
A hydrologic study was conducted to investigate groundwater-lakewater interactions around Topaz Lake, Nevada, where an alluvial aquifer is hydraulically connected with the off-stream storage reservoir. Basic objectives of ...
Removal of heavy metal ions from acid mine drainage by modified ferrite co-precipitation process
(University of Nevada, Reno, 1994)
Acid mine drainage (AMD) is a large environmental problem facing mining, mineral processing and coal preparation plants. Due to long term oxidation and weathering, sulfide bearing tailings and overburdens generate sulfuric ...
Gravity-driven instability in unsaturated fractures
(University of Nevada, Reno, 1993)
The stability of infiltration flow into inclined, unsaturated fractures has been studied. An initially dry natural tuff fracture is used to demonstrate that gravity-driven instability is a separate process form heterogeneity ...
Analysis of the Northern Dixie Valley groundwater flow system using a discrete-state compartment model
(University of Nevada, Reno, 1987)
A three-dimensional, steady-state flow model of the northern half of the Dixie Valley groundwater flow system, was constructed utilizing the theory of discrete-state compartment models and calibrated with spatial distributions ...
Analysis of techniques for estimating potential recharge and shallow unsaturated zone water balance near Yucca Mountain, Nevada
(University of Nevada, Reno, 1990)
Partitioning of precipitation was examined over two years to evaluate moisture potentially available for groundwater recharge at Yucca Mountain. Monitoring soil moisture movement was accomplished using Time Domain Reflectometry.
Controls on ground water chemistry in central and western Nevada
(University of Nevada, Reno, 1982)
Geochemical evolution of waters from the semi-arid western Great Basin and parts of the Sierra Nevada was analyzed using common techniques for computation of ionic speciation, classification, R-mode factor analysis and an ...
