  • Accuracy assessment of LiDAR point cloud geo-referencing

    Creator:
    Williams, Keith E.
    Abstract:
    Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of...

  • The Effects of Temperature on Electrical Resistivity Measurements of Concrete

    Creator:
    Coyle, Alex T.
    Abstract:
    Measuring resistivity as a method to calculate formation factor is becoming a popular way to evaluate transport properties of concrete. Resistivity measurements are dependent on multiple factors including the resistivity of the pore solution, leaching effects, the degree of saturation of the specimen, the age of the specimen (degree of...

    Creator:
    Kirkham, William J.
    Abstract:
    There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

  • Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

    Creator:
    Converse, Jordan D.
    Abstract:
    With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...

    Creator:
    Nichols, William E.
    Abstract:
    The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...

  • Fractal solutions to the long wave equations

    Creator:
    Ajiwibowo, Harman
    Abstract:
    The fractal dimension of measured ocean wave profiles is found to be in the range of 1.5-1.8. This non-integer dimension indicates the fractal nature of the waves. Standard formulations to analyze waves are based on a differential approach. Since fractals are non-differentiable, this formulation fails for waves with fractal characteristics....

  • Numerical and physical modeling of wave forces on A-Jacks units

    Creator:
    Wise, Larry
    Abstract:
    A numerical model is developed to estimate wave forces on A-Jacks armor units. The forces include drag, inertia, buoyancy, and slamming as the unit penetrates the free surface. The wave force model is used to determine the rigid body motions of the units. Bulk forces on a matrix of units...

  • The measurement of nearshore bathymetry on intermediate and dissipative beaches

    Creator:
    Côté, Jessica Magee
    Abstract:
    In 1996, Beach et al. first proposed the idea of mounting an echo-sounder on a Waverunner to measure nearshore beach profiles. This thesis discusses the Coastal Profiling System, an extension of the original work, which has been utilized to measure nearshore bathymetry at selected sites along the coasts of North...

  • Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

    Creator:
    Forfinski-Sarkozi, Nicholas A.
    Abstract:
    Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

    Abstract:
    Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...

    Abstract:
    A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...

    Abstract:
    Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

    Wave breaking in the surf zone is an important forcing mechanism on the generation of nearshore currents and in the driving of sediment transport. At the same time, wave breaking can have significant spatial and temporal variability that needs to be accounted for in the description of nearshore processes. Remote...
