  • Remote Sensing of Nearshore Hydrodynamic and Morphodynamic Processes

    Creator:
    O'Dea, Annika M.
    Abstract:
    The use of remote sensing techniques in coastal science and engineering has rapidly increased in the past few decades. This dissertation outlines new remote sensing tools using two remote sensing technologies (lidar and X-band marine radar) along with two nearshore hydrodynamic and morphodynamic analyses supported or motivated by these remote...

  • A predictive model for environmental fate and transport of the toxicity of leachates from highway construction and repair materials

    Creator:
    Quigley, Marcus M.
    Abstract:
    Recent concern over the potential environmental impact of highway construction and repair materials on surface and ground waters has lead to extensive laboratory screening and subsequent testing of a set of new materials and waste amended mixes. As part of Phase II of a three-phase project for the National Cooperative...

  • Breaking Waves Offshore: Measurements and Modeling of Energy Dissipation

    Creator:
    Ticona Rollano, Fadia M.
    Abstract:
    In the presence of strong winds, ocean surface waves dissipate significant amounts of energy by breaking. Here, breaking rates and wave-following turbulent dissipation rate measurements are compared with numerical WAVEWATCH III estimates of bulk energy dissipation. At high winds, the measurements suggest that turbulent dissipation becomes saturated, however the modeled...

  • The use of LiDAR to identify forest transportation networks

    Creator:
    Beck, Storm J. C.
    Abstract:
    The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...

  • Stochastic analysis of a nonlinear ocean structural system

    Creator:
    Lin, Huan
    Abstract:
    Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...

  • Abiotic and biological transformation of TBOS and TKEBS, and their role in the biological transformation of TCE and c-DCE

    Creator:
    Vancheeswaran, Sanjay
    Abstract:
    At Site-300, Lawrence Livermore National Laboratory (LLNL), CA, trichloroethene (TCE) is present along with tetraalkoxysilanes such as tetrabutoxysilane (TBOS) and tetrakis(2-ethylbutoxy) silane (TKEBS), as subsurface contaminants. Intrinsic transformation of TCE to cis-dichloroethene (c-DCE) was observed in the groundwater at locations co-contaminated with TBOS or TKEBS. Attenuation of TBOS and TKEBS...

  • Behavior of gypsum-sheathed cold-formed steel wall stud panels

    Creator:
    Lee, Young-ki
    Abstract:
    This study consists of three parts: 1) Part A: Limiting Height Evaluation for Composite Wall Tests, 2) Part B: Mid-Span Deflection Evaluation for Composite Wall Tests, and 3) Part C: Nominal Axial Strength Evaluation for Wall-Braced Wall Stud Columns. The purpose of Part A is to develop experimentally-based limiting heights...

  • 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...

  • Depth estimation and frontal imaging via X-band marine radar

    Creator:
    Honegger, David Andrew
    Abstract:
    This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

    Abstract:
    The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...
