A stable isotope investigation of nitrate contamination at Many Devils Wash, Shiprock UMTRCA Site, Shiprock, NM
The Navajo Mill was a uranium and vanadium ore processing site located in Shiprock, NM, on a terrace adjacent to the San Juan River. The leaching of ore with ammonium and sulfuric acid introduced large amounts of contaminants ...
Fundamentals of aquifer multiphase flow in response to inertial and viscous forces
(University of Nevada, Reno, 1994)
Fundamentals of aquifer multiphase flow in response to inertial and viscous forces have been examined. A new law is introduced which assumes the skeletal matrix behaves a non-Newtonian flow that is coupled with pore fluid ...
Chemical variations of the Truckee River from Lake Tahoe to Truckee, California during low flow
(University of Nevada, Reno, 1982)
Data suggests that approximately 30 percent of the base flow in the Truckee River was derived from surface water tributary contribution and 70 percent was groundwater contribution between Tahoe City and Truckee, California. ...
Relationships between streamflow and groundwater in Humboldt River Valley near Winnemucca, Nevada
(University of Nevada, Reno, 1969)
The physical and hydrologic relationships between the Humboldt River and the groundwater reservoir are examined in this study for the reach of river between Comus and Rose Creek gaging stations.
An LP embedded simulation model for conjunctive use management optimization
(University of Nevada, Reno, 1983)
Equations for groundwater flow and surface water continuity have been embedded in a linear programming hydraulic management model. The embedding method is useful for small problems over a limited number of time steps, but ...
Numerical simulation of artificial recharge in Cold Spring Valley, Nevada
(University of Nevada, Reno, 1981)
A steady-state, finite element model was used to simulate the Cold Spring Valley groundwater flow system. The primary limiting factor to any artificial recharge scenario in Cold Spring Valley is the response of the water ...
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.
Aquifer storage characteristics of Paleozoic carbonate rocks in southeastern Nevada estimated from harmonic analysis of water-level fluctuations
(University of Nevada, Reno, 1992)
One- and three-dimensional theories of aquifer dilation due to earth tides are reviewed to determine aquifer storage characteristics. Water-level records for eleven wells and one open fault that penetrate the aquifers and ...
Characterization of present and possible future (wetter) climatic regimes utilizing the historical climatic record and an analogue technique in the southern Great Basin
(University of Nevada, Reno, 1989)
The historical climatic record and an analogue technique were used to characterize present and possible future (wetter) climatic regimes in the southern Great Basin. Results of this study provide useful climatic input data ...
Rare earth elements in terrestrial waters: speciation modelling in acidic to alkaline waters
(University of Nevada, Reno, 1993)
Three manuscripts are presented describing the rare earth element (REE) concentrations and behavior in terrestrial waters. These studies suggest that the pH, rock geochemistry, and the formation of stable REE complexes ...
