  • The Application of Machine Learning Techniques on Marine Science Models

    Creator:
    Ellenson, Ashley
    Abstract:
    A variety of stakeholders require information about marine systems. In the open ocean, pilots of marine vessels require knowledge about environmental conditions for safe passage and route planning. On the coastline, communities rely on information about nearshore dynamics to increase safety from coastal hazards such as nearshore pollutants, coastal erosion,...

  • 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...

  • Modeling sediment transport, channel morphology and gravel mining in river bends

    Creator:
    Nam, Ilgi
    Abstract:
    A technique is developed and tested to analyze the interaction of flowing water, bed topography, and bedload sediment transport in meandering channels where gravel bars are removed. The method relates the local velocity distribution, bed shear stress and sediment transport conditions to the local bed configuration in river bends before...

  • 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)...

  • 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...

  • Deterministic and stochastic behaviors of a piecewise-linear system

    Creator:
    Mha, Ho-Seong
    Abstract:
    The (nonlinear) response behavior of a piecewise-linear system is investigated under both deterministic and stochastic excitations in this study. A semi-analytical procedure is developed to predict the system behavior by evaluating the joint probability density functions of the Fokker-Planck equations of the stochastic piecewise-linear system under random excitations via a...

  • 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...

  • Dynamic properties of naturally frozen Fairbanks silt

    Creator:
    Wilson, Charles Ralph
    Abstract:
    As part of a long term study to evaluate the dynamic properties of naturally frozen soils, resonant frequency and cyclic triaxial tests were conducted on Fairbanks silt samples from the U.S. Army Cold Regions Research and Engineering Laboratory Permafrost Tunnel, Fox, Alaska. The test methods subject right cylindrical test specimens...

  • Dynamics of the nearshore wave bottom boundary layer

    Creator:
    Foster, Diane Lyn
    Abstract:
    This thesis presents an examination of the nearshore wave bottom boundary layer under conditions of significant sediment response. Using both field observations and simple models, the response of the bottom boundary layer to random waves is shown to have a complex behavior. First, the linearized wave bottom boundary layer governing...

  • Quantifying the Relative Role of the Key Drivers of Coastal Dune Evolution: Observations and Simulations Across a Range of Time and Space Scales in Cape Lookout National Seashore, North Carolina

    Creator:
    Hovenga, Paige A.
    Abstract:
    Coastal dunes provide a diverse set of ecosystem services including coastal protection against destructive surge and waves during storm events. Dunes are constantly evolving through various stages of response to storm events and post-storm recovery at rates that vary due to a range of drivers including pre-existing morphology, environmental forcing...
