Quantification of advection and dispersion in lateral subsurface flowpaths at the hillslope-scale

Creator:: Victory, Nichole I.
Abstract:: It is becoming increasingly important to understand fundamental hillslope-scale hydrological processes. Most hillslope-sale transport experiments have generally focused on conceptual findings or other aspect of flow behavior, rather than the quantification of the mass transport mechanisms of advection and dispersion. When the velocities have been quantified, dispersion has been mentioned...

Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

A kinetic model for dissolved gas transport in the presence of trapped gas

Creator:: Donaldson, Jeremy H.
Abstract:: Understanding the processes involved in the transport of dissolved gas plumes in groundwater aquifers is essential for comprehending the effect that these transport processes can have on site characterization and remedial design applications. Previous laboratory and field studies have indicated that dissolved gas transport in groundwater can be greatly affected...

Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

Creator:: Sapp, Mandy M.
Abstract:: Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....

Watershed modeling at Yucca Mountain, Nevada

Creator:: Britch, Michael J.
Abstract:: Studies are currently underway to determine the suitability of Yucca Mountain in Nevada as the nation's first high-level nuclear waste repository. Values of net infiltration are required to determine pre-waste emplacement groundwater travel times and the performance of the repository as a waste containment system. The objective of this study...

Groundwater flow model for the lower Malheur Basin near Ontario, Oregon

Creator:: Walker, David S.
Abstract:: The shallow, poorly-confined, sand and gravel aquifer underlying the lower Malheur River basin is contaminated by nitrate and metabolites of the herbicide dimethyl tetrachloroterephthalate (DCPA), first detected in 1983 and 1985, respectively. The aquifer supplies water for the Ontario municipal water system, domestic and industrial uses, and irrigation. In response...

Microcosm study of enhanced biotransformation of vinyl chloride to ethylene with TCE additions under anaerobic conditions from Point Mugu, California

Creator:: Pang, Incheol Jonathan
Abstract:: This microcosm study demonstrated the enhanced anaerobic transformation of vinyl chloride (VC) to ethylene. A previous microcosm study from Point Mugu site showed the accumulation of VC due to the slow transformation step of VC to ethylene. To overcome the rate-limiting step, two laboratory experiments tested the effect of trichloroethylene...

Modeling of ammonia losses in sprinkler application of animal wastes

Creator:: Pote, Jonathan W. (Jonathan Woodrome)
Abstract:: A model to predict ammonia losses from sprinkler applied animal wastes was developed; in order to accomplish this, a review of literature was performed to determine possible methods of predicting ammonia losses during sprinkling. As adaptability to a large variety of situations was considered of maximum importance, the number of...

Shear strengthening reinforced concrete bridge girders using near-surface mounted titanium alloy bars

Creator:: Knudtsen, Jonathan
Abstract:: Aging and deficient infrastructure has become a major problem throughout the world. This is particularly evident in the case of reinforced concrete (RC) bridges. The cost of replacing these bridges is often prohibitive, thus engineers must find ways to strengthen them. Many older RC bridges predate the modern understanding of...
