  • A stochastic precipitation event model for use in erosion simulations

    Creator:
    Istok, J. D.
    Abstract:
    Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

  • Radar and Optical Remote Sensing of Submesoscale Frontal Features

    Creator:
    Simpson, Alexandra J.
    Abstract:
    The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

  • Analysis of diagonally cracked conventionally reinforced concrete girders in the service load range

    Creator:
    Robelo, Melissa J.
    Abstract:
    Performance evaluation of conventionally reinforced concrete (CRC) bridge superstructure elements with diagonal cracks is of interest to the bridge engineering community. Standardized methods to predict service-level stress magnitudes in cracked bridge girders under combined bending and shear forces are not available. An analysis procedure was developed to determine the response...

  • Applications of Marine Radar Wave Observation Systems

    Creator:
    Meskill, Shay J.
    Abstract:
    This project utilized both shore-based and shipboard commercial marine radar technology to collect wave statistics. In the first application a shore-based system was installed at Yaquina Bay in Newport, Oregon in order to collect real-time wave information. This information was collected under the auspices of the Northwest Association of Networked...

  • Quantification of landslide movement in a forested environment

    Creator:
    Conner, Jeremy C.
    Abstract:
    Landslides are an insidious natural hazard, which can result in significant damage to public infrastructure. Limited monitoring tools are available, particularly tools suitable for use in forested environments. These tools often only allow a few locations across the slide to be monitored. Terrestrial Laser Scanning (TLS) shows promise as a...

  • Ultimate bearing capacity of shallow footings on plastic silt

    Creator:
    Newton, Vernon C.
    Abstract:
    The usual approach to calculation of the ultimate bearing capacity of plastic silt is to assume no porewater drainage occurs during the loading period. The coefficient of permeability of plastic silt is generally significantly larger than clay; therefore, partial drainage of porewater may occur during the loading period. This study...

  • Mooring analysis of the Ocean Sentinel through field observation and numerical simulation

    Creator:
    Baker, Joshua L.
    Abstract:
    This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...

  • Vertical jet diffusion in non linear density stratified fluid

    Creator:
    Baumgartner, D. J. (Donald John), 1933-
    Abstract:
    The simplified equations of motion proposed by Morton to determine the extent of vertical travel of a forced plume in a linear density stratified environment were re-written and solved in a way which allowed them to be applied to any non linear profile of density. For application to any specific...

  • Influence of Uncertainties in Terrestrial Laser Scanning on Structural Reliability and Bridge Load Rating

    Creator:
    Loving, Carly K.
    Abstract:
    To ensure the safety of the nation’s bridges, the National Bridge Inspection Standards (NBIS) require all bridges to undergo routine load rating analyses to assess their structural capacity. Accurate geometric information for each structure is necessary for load rating analyses. This information is typically ascertained from as-built plans. Still, when...

  • On the Imaging of Rip Currents in X-band Radar

    Creator:
    Kloster, Rebecca
    Abstract:
    Rip currents pose a serious danger to visitors of bathing beaches; they are also an important process in surf zone circulation. Haller et al. [2014] demonstrated that shore-based X-band radar can be used to compliment in situ measurements of rip currents. However, little is known of the underlying radar imaging...
