The geology of radioactive mineral occurrences near Marietta, Nevada
(University of Nevada, Reno, 1977)
Near Marietta, Nevada, uranium that originally formed in the area in connection with granitic plutonic intrusive rocks, has been exposed to the surface and is being released into the region's hydrologic cycle.
Modeling the transient horizontal movement of an aquifer based on the Gersevanov-Darcy law
(University of Nevada, Reno, 1991)
The velocity of solids, displacement of solids, and volumetric strains related to an aquifer are calculated in response to discharge and injection wells using a numerical model which incorporates the Gersevanov - Darcy law.
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.
Sorption of cesium and strontium by arid region desert soil
(University of Nevada, Reno, 1984)
The sorption and ion exchange properties of nonradioactive cesium and strontium were studied in this investigation. Ion exchange studies have shown that the studied soil sorbs cesium preferentially relative to strontium, ...
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.
Characterizing hierarchical heterogeneous porous media using multiscale information
(University of Nevada, Reno, 1994)
A wavelet transform based method of (inverse) modeling large scale non-stationary heterogeneities is developed and examined to provide a better understanding of contaminant dispersion in large scale hydrogeologic problems.
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, ...
A hydrologic and economic model for the optimization of irrigation water utilization on the Humboldt River system
(University of Nevada, Reno, 1978)
Given the present cost and price structures, the upstream storage project in combination with the transfer of water rights to bench lands is not economically feasible.
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.
The dissolution kinetics of fibrous amphibole minerals in water
(University of Nevada, Reno, 1971)
Short term experiments lasting for thirty minutes on dissolution of amosite and crocidolite gave congruent dissolution. The rate of dissolution was found to depend on pH, surface area and stirring rate. The kinetics of ...
