  • Of Planes and Plumblines: Map Projections and Differential Leveling in a GNSS-based 3D Geodetic Framework

    Creator:
    Dennis, Michael L.
    Abstract:
    Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...

  • The evaluation of the field vane shear strength analysis of the Glen Aiken creek embankment failure

    Creator:
    Clarke, James Dennis
    Abstract:
    A post-failure investigation of a highway embankment constructed over organic and sensitive subsoils was made with a series of field vane tests. The results indicated that the embankment was quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...

  • Diffusion in a variable density liquid under conditions of turbulent, steady flow

    Creator:
    Harris, Dennis Roy
    Abstract:
    The diffusion process in a variable density, turbulent flow is a factor which greatly influences the waste disposal characteristics of tidal estuaries. Waste disposal from cities and industries, is posing an increasing threat to the estuarine environment. Accurate prediction of the effects of proposed waste outfalls in well-mixed estuaries (which...

  • Nutrients in runoff from spray irrigation of swine wastes

    Creator:
    Taylor, Dennis William
    Abstract:
    Major emphasis of this research study involved the evaluation of nutrient transport by overland flow. Samples gathered at various distances relative to a swine-waste spray irrigation system were used for the nutrient evaluation. As a result of this study, the following conclusions are made: 1. It is improbable that the...

  • The Design of a Roof Truss for the Proposed Drill Shed at the Oregon Agricultural College

    Creator:
    Thompson, Ralph Infield
    Abstract:
    By an appropriation of the Oregon Legislature of it becomes possible for the Oregon Agricultural College to build a drill shed, a thing long needed by this institution. Dennis, Hendricks and Tobey, architects of Portland, submitted plans for this drill shed and in designing the truss for this building we...

  • Fate of THMs in Columbia River basalts during aquifer storage and recovery

    Creator:
    Bertrand, Danelle
    Abstract:
    Use of basalt aquifers for aquifer storage and recovery (ASR) systems is increasing in the Pacific Northwest due to the large aerial extent of the Columbia River Basalt Group and the suitability of basalts as ASR reservoirs. However, the degradation of trihalomethanes (THMs), potentially carcinogenic disinfection by-products present in the...

  • Development of performance based test procedures for asphalt mixtures

    Creator:
    Kliewer, Julie E.
    Abstract:
    In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

  • Deformation-based seismic design models for waterfront structures

    Creator:
    Yang, Dong-Shan
    Abstract:
    Recent experience demonstrates that waterfront structures are vulnerable to earthquake damage. The poor seismic performance of these facilities has been primarily due to liquefaction of backfill and/or foundation soils and the lack of seismic design standards for waterfront structures. The seismic performance of waterfront structures is a key issue in...

  • Interstitial fluid mixing in estuarine benthic sediments

    Creator:
    Boyce, Allen R.
    Abstract:
    A method of measuring interstitial fluid mixing rates for evaluation of exchange between pore water of estuarine benthic sediments and the overlying water in a bay is presented. Pore water movement is monitored by reducing conductivity of the interstitial fluid within a zone of the benthic sediment to a depth...
