  • 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...

  • Efficient Topobathymetric Mapping and 3D Spatial Analysis of Estuaries Using Multi-Platform, Multi-Temporal Data

    Creator:
    Lambert, Selina E.
    Abstract:
    Frequent 3D spatial mapping of estuaries is critical to understanding and modeling changes that can impact ecological health (e.g., water quality) and ecosystem services (e.g., aquaculture, nutrient cycling, and shoreline stabilization). However, obtaining accurate, repeat topobathymetric data for estuaries is a major challenge. Because shallow estuaries are typically not used...

  • Evaluation of estuarine channel conditions in Coos Bay, Oregon using side-scan sonar

    Creator:
    Hartman, Gregory L.
    Abstract:
    Side-scan sonar records in Oregon's Coos Bay estuary navigation channels were obtained at intervals of two to three months during the November 1974 - October 1975 time period from Coos Bay Channel Mile 11+50 to 15+20, and from a reach in the Marshfield Channel. A limited side-scan survey effort was...

  • 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...

  • Radiometric Calibration of EAARL‐B Bathymetric Lidar Data

    Creator:
    Wilson, Nicholas C.
    Abstract:
    The Experimental Advanced Airborne Research Lidar ‐ B (EAARL‐B), which was built and deployed by the U.S. Geological Survey (USGS) in 2014, is a novel topographic‐bathymetric lidar system. While retaining a number of features that were pioneered in the original National Aeronautics and Space Administration (NASA) EAARL system (e.g., low...

  • Improving the Performance of High Early Strength Concrete by Controlling Self-Desiccation and Mitigating Shrinkage

    Creator:
    Wilson, Cameron A.
    Abstract:
    High early strength (HES) concrete is becoming increasingly used to repair damaged concrete pavement sections. The use of HES concrete enables the repaired pavement to be opened to traffic within hours of placing the concrete. A common approach used for the rapid repair of concrete pavement consists of closing a...

  • Behavior of a 1/6th scale, two-story, wood framed residential structure under surge wave loading

    Creator:
    Wilson, Jebediah
    Abstract:
    The goal of this study was to develop an understanding of the nature of surge wave loading on wood framed residential structures for a variety of building configurations and test conditions. The objectives of the study were: (1) to measure forces on a 1/6th scale wood framed residential structure, (2)...

  • Long Wave Amplification in a Coral-Reef Lagoon

    Creator:
    Bheeroo, Vivek Anand
    Abstract:
    A series of laboratory experiments were conducted to study the wave field in the inner lagoon excited by ‘long’ incident waves. Three cases were considered: Cases A, B and C presenting incident waves of wavelength with factors of 1, 2 and 2.5 times the width of the reef respectively. The...

  • Properties of marginal aggregates treated with asphalt emulsion

    Creator:
    Evans, Gary L.
    Abstract:
    The purpose of this report is to address the problem of supplying construction aggregates to Oregon's coastal areas that are currently, or will in the near future, be deficient of good quality materials. This is done primarily by studying methods of utilizing marginal aggregates that are abundantly available in the...

  • The analysis of directional wave spectra from current and pressure measurements

    Creator:
    Lin, Li-hwa
    Abstract:
    Directional wave spectra have been estimated in this study based upon simultaneous subsurface measurements of current and pressure. Two previously developed methods, the stochastic and deterministic approaches, have been reviewed and restudied. It is demonstrated by means of the Correlation Theorem that the stochastic and deterministic approaches are, under certain...
