  • The use of polymers for better settling in domestic waste treatment systems

    Creator:
    Houck, George Campbell
    Abstract:
    The author presents a "state of the art" of the use of polymers for better settling in domestic waste treatment and evaluates the published research in the field. Polymers have only recently been used to obtain better settling in domestic waste treatment. Due to the number of polymer types available...

  • Depth-dependence of surf zone eddies : a study at Duck, NC

    Creator:
    Aiken, Rebecca A.
    Abstract:
    Surf zone eddies (f < 0.01 Hz) are important in nearshore mixing, shoreline erosion, the distribution of pollutants, and ecological processes, such as offshore transport of larvae. Surf zone eddies have traditionally been treated as two-dimensional features with horizontal length scales larger than the local water depth. Studies by Lippmann...

  • An evaluation of coastal Oregon's marginal aggregates

    Creator:
    Clemmons, Gregory H.
    Abstract:
    Coastal Oregon is deficient in quality construction aggregates. There is, however, an abundance of lower quality, or marginal, aggregate available for construction purposes. An evaluation of these marginal aggregates is the purpose of this paper. There are four classes of marginal rocks found on the Oregon Coast. Basalts, high in...

  • 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...

  • Collection and analysis of evaporative flux data for various climates

    Creator:
    Katul, Gabriel
    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

  • Engineering properties of Oregon and Washington coast range soils

    Creator:
    Alto, Jalmer V.
    Abstract:
    Landslides are frequent in the steep forested regions of the Oregon and Washington coastal mountain ranges. The need for forest products has resulted in increasing logging activity in these marginally stable areas. The occurrence of landslides has increased, which in turn has focused greater interest in slope stability management. Of...

  • Tidal range changes in the Delaware Bay : past conditions and future scenarios

    Creator:
    Hall, George F.
    Abstract:
    Throughout the Holocene, appreciable changes in bathymetry are hypothesized to have resulted in large changes to tidal datums in coastal and estuarine areas. An understanding of tidal change is an important contribution to the knowledge of relative historical sea-level change and future coastal planning. To test this hypothesis, the Advanced...

  • Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

    Creator:
    Cheng, Tiffany Kay
    Abstract:
    Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

  • Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

    Creator:
    Kalmbacher, Kirk D.
    Abstract:
    The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...
