  • Flow slide control with slope revetments

    Creator:
    Narkiewicz, Steven Arthur
    Abstract:
    This paper examines the response of submerged model sand slopes to vibration and the beneficial effects of placing rock revetments on the face of the slope to prevent flaw slides. Pore water pressure response and deflection were used as a criteria for stability in an attempt to relate stability with...

  • Roughness and geometry effects of engineered log jams on 1-D flow characteristics

    Creator:
    Valverde, Rachelle S.
    Abstract:
    The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

  • Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

    Creator:
    La Nier, Justin
    Abstract:
    Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

  • Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

    Creator:
    Converse, Jordan D.
    Abstract:
    With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...

  • 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...

  • Trade-offs between geometric design standards and safety for low volume roads

    Creator:
    Kornsombut, Aram
    Abstract:
    Geometric design standards have not been developed specifically for low volume roads. Design standards and criteria are extrapolated from higher standard roadways that are often not relevant to low volume roads. Safety is a primary criterion used for selection of design standards along with economic, financial, social and environment factors....

  • Computerized safety analysis technique for secondary highways

    Creator:
    Nichols, Kevin Scott
    Abstract:
    Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...

  • Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

    Creator:
    Michalsen, Mandy M.
    Abstract:
    Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

  • A procedure to identify and evaluate forest arterial and collector road networks

    Creator:
    Kehr, Richard H.
    Abstract:
    This thesis presents a procedure to identify and evaluate forest arterial and collector networks. The procedure identifies those decision criteria important in evaluating both the arterial and collector networks and the specific facilities identified on these networks. The procedure incorporates the decision criteria and results from network and facility analysis...

    Creator:
    Alyousef, Hashim A.
    Abstract:
    Bioretention facilities are emerging as a popular way to deal with stormwater runoff in urban environments and address its concerns. Real-time sensors installed in bioretention facilities aid in understanding the performance and feasibility of such facilities over time. A bioretention facility in Corvallis, Oregon was monitored for a study period...
