  • Estuarine sediment controls on trace metal distributions

    Creator:
    Davies-Colley, Robert J.
    Abstract:
    Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...

  • Adsorption of hexavalent and trivalent chromium to a clayey silt soil : batch kinetic and equilibrium studies

    Creator:
    Bean, Gregory R.
    Abstract:
    Chromium, an element of widespread use, is toxic in some forms. Improper disposal of waste chromium products has resulted in contamination of many sites throughout the United States, including the United Chrome Products Superfund site in Corvallis, Oregon. A better understanding of chromium chemistry is needed to facilitate the remediation...

  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Irregular points in wavemaker boundary value problem

    Creator:
    Tanaka, Yoshihiro
    Abstract:
    A global solution is presented that accurately accounts for the singular behavior at all irregular points. The linearized boundary value problem in a semi-infinite strip in the physical plane is transformed into a smooth unit disk by two successive conformal mappings. The global solution results from a Fredholm integral equation...

  • Evaluation of alternate surfacing systems for temporary and intermittent use roads

    Creator:
    Takallou, Mojtaba B.
    Abstract:
    The purpose of this study was to provide the USDA-Forest Service, Bureau of Land Management (BLM), and other agencies or industries that may deal with temporary and intermittent use roads with the necessary background information for the identification, economic evaluation, and selection of the alternate surfacing systems and to determine...

  • The performance of drivers with physical limitations at T-intersections

    Creator:
    Hunter-Zaworski, Katharine M.
    Abstract:
    The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

  • Evaluation of finite element techniques for soil reinforcement applications

    Creator:
    Berg, Ryan Robert
    Abstract:
    A literature review and a computer study are conducted to identify the requirements of finite element programs for the specific use of discrete analyses of reinforced soil structures. The utility of six commercially available programs are appraised with respect to the identified requirements. The results of the study are directed...

  • Evaluation of cold in-place recycling of asphalt conrete pavements in Oregon

    Creator:
    Scholz, Todd
    Abstract:
    Significant use of cold in-place recycling (CIR) has occurred in Oregon since 1984 as an alternative to other rehabilitation techniques or to the reconstruction of distressed asphalt concrete (AC) pavements. Due to the initial success of the projects cold recycled during 1984-85, the Oregon Department of Transportation (ODOT) and Oregon...
