  • Curriculum synthesis and amelioration : a case study of undergraduate civil engineering

    Creator:
    Hamernik, Robert E.
    Abstract:
    The dynamic philosophy of education as applied to the undergraduate Civil Engineering program has been influenced by such factors as the introduction of new theories, the demands and needs of our society and the personnel responsible for teaching. These changes are reflected in the curriculum as witnessed by a historical...

  • Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

    Creator:
    Jensen, Robert E.
    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...

  • Spatial and temporal characteristics of groundwater levels adjacent to beaver ponds in Oregon

    Creator:
    Sharps, Diana E.
    Abstract:
    This study was undertaken to evaluate the spatial and temporal characteristics of riparian groundwater tables adjacent to beaver ponds. The research was conducted in two parts; in the first portion a two-dimensional, finite-difference computer model was developed and utilized to simulate groundwater elevations through time in pond-adjacent aquifers. Two types...

  • 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...

  • 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...

  • Of Planes and Plumblines: Map Projections and Differential Leveling in a GNSS-based 3D Geodetic Framework

    Creator:
    Dennis, Michael L.
    Abstract:
    Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...

  • Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

    Creator:
    Chen, Min-Chu
    Abstract:
    A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

  • Application of the generalized Melnikov method to weakly damped parametrically excited cross waves with surface tension

    Creator:
    Fadel, Suzan M.
    Abstract:
    The Wiggins-Holmes extension of the generalized Melnikov method (GMM) is applied to weakly damped parametrically excited cross waves with surface tension in a long rectangular wave channel in order to determine if these cross waves are chaotic. The Lagrangian density function for surface waves with surface tension is simplified by...

  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Comparison of Vermont and Oregon statutory land surveyor laws

    Creator:
    Norton, Robert Leon
    Abstract:
    Land use planning, zoning, and subdivisions are integrally tied to the land resource. The need for a land surveyor and for statutes which govern his operation when working in these areas is stressed. A brief history of Vermont and Oregon, illustrating the role of land surveys on settlement, is given....
