  • 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...

  • Multivariate geostatistical analysis of groundwater contamination by pesticide and nitrate

    Creator:
    Smyth, Jeffrey D.
    Abstract:
    A field study was conducted to determine the applicability of multivariate geostatistical methods to the problem of estimating and simulating pesticide concentrations in groundwater from measured concentrations of nitrate and pesticide, when pesticide is undersampled. Prior to this study, no published attempt had been made to apply multivariate geostatistics to...

  • 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....

  • Precipitation estimation in mountainous terrain using multivariate geostatistics

    Creator:
    Hevesi, Joseph A.
    Abstract:
    Estimates of average annual precipitation (AAP) are-needed for hydrologic modeling at Yucca Mtn., Nevada, site of a proposed, high-level nuclear waste repository. Historical precipitation data and station elevation were obtained for stations in southern Nevada and southeastern California. Elevations for 1,531 additional locations were obtained from topographic maps. The sample...

  • 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...
