  • The static and dynamic analysis of discretely represented moorings and cables by numerical means

    Creator:
    Dominguez, Richard Frank
    Abstract:
    Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

  • Effect of deposits in Columbia Slough on algae growth in Smith and Bybee lakes

    Creator:
    Sobolewski, William Joseph
    Abstract:
    Currently, the Port of Portland is developing a 9, 410 acre area at the confluence of the Columbia and Willamette Rivers in Multnomah County, Oregon. This area will be developed for industrial, commercial, and recreational use. The recreational development in the North Portland Peninsula area, including the Rivergate Industrial District,...

  • Effects of pressure and deposit thickness on the stabilization rate of benthic marine sludge deposits

    Creator:
    Muellenhoff, W. P.
    Abstract:
    The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

  • Real-time Dynamic Schedule Updating Through Integrated Lean Construction Methods

    Creator:
    Lotti de Oliveira Paula, Gustavo
    Abstract:
    Planning and management methods in construction need to constantly evolve to keep pace with the growing demand and complexity of work in increasingly competitive environments. This need for innovation and process improvement has attracted lean construction philosophy in industry management practice. Lean has been used in the construction industry to...

  • Coupled response of compliant offshore platforms

    Creator:
    Young, Raymond A.
    Abstract:
    A three dimensional finite element analysis is developed which is capable of simulating the coupled static and dynamic behavior of compliant ocean structures. Nonlinearities which result from large-deflection, reduced or zero stiffness in compression, and the nonconservative fluid loading are considered. The spatial variation of fluid loading is also addressed....

  • Influence of Concrete and Construction Parameters on Chloride Test Measurements and Critical Chloride Threshold Limits

    Creator:
    Vaddey, Naga Pavan
    Abstract:
    The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...

  • Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

    Creator:
    Parker, Kai A.
    Abstract:
    Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

  • Numerical Studies on Fluid-Structure Interaction and Applications

    Creator:
    Chen, Ming
    Abstract:
    Fluid-structure interaction (FSI) has been of significant research interest worldwide over the past several decades because of its variety of applications in both offshore and coastal engineering. Researchers analyzing FSI systems rely heavily on experimental tests in model scale in laboratories or large-scale sea trials. However, these tests are often...

  • Air photo analysis of waste dispersion from ocean outfalls

    Creator:
    James, Wesley Pierce
    Abstract:
    Aerial photography provides a method of analyzing dispersion of wastes that are discharged into the ocean. This method is more comprehensive than conventional boat sampling in dispersion studies. The photographic technique permits waste concentrations to be measured throughout the plume in one instant; thereby allowing the diffusion analysis to be...

  • Reducing sediment production from forest roads during wet-weather use

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...
