  • Numerical computation of free surface water flow

    Creator:
    Kuhnert, Jorg
    Abstract:
    The present thesis is a report of investigations on a model for computing the water flow in the wave tank of the OSU Wave Laboratory. A wave board, established at one end of the 100 m long, 4 m wide and 6 m deep wave tank, produces water waves by...

  • 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....

  • Flexible membrane wave barrier

    Creator:
    Thompson, Gary O.
    Abstract:
    This report details the derivation of an analytical model for a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column by a moored cylindrical buoy on the free surface and fixed to a hinge at the seafloor. The analytical model combines...

  • Interaction of water waves and deformable bodies

    Creator:
    Broderick, Laurie L.
    Abstract:
    A time-domain model was developed to predict the fluid/structure interaction of a three-dimensional deformable body in a fluid domain subject to long-crested finite amplitude waves. These nonlinear waves induce transient motion in the body. In turn, the interaction of the body with the waves modifies the wave field, causing additional...

  • An analysis of wave forces on prototype walls under tsunami loading

    Creator:
    Oshnack, Mary Elizabeth
    Abstract:
    This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

  • An experimental study and a three-dimensional numerical wave basin model of solitary wave impact on a vertical cylinder

    Creator:
    Zhang, Wenbin
    Abstract:
    An experiment on solitary wave impact on a vertical cylinder was conducted in the three-dimensional wave basin at the Oregon State University Hinsdale Wave Research Laboratory. The cylinder was designed using mechanic principles and finite element analysis techniques to enable accurate measurement of horizontal force and overturning moment. Video data...

  • Data assimilation for prediction of shallow water flows with uncertain bathymetry

    Creator:
    Wilson, Gregory W.
    Abstract:
    A new method is introduced for incorporating bathymetric uncertainty into predictions of nearshore and river flows (i.e., unstratified flows primarily forced by pressure and radiation stress gradients). The method involves the use of the ensemble Kalman filter (EnKF) as a parameter estimation scheme, where the parameter to be estimated is...

  • 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...

  • Shear waves in a circular wave basin

    Creator:
    Berkery, Lynn A.
    Abstract:
    Shear waves, which are instabilities of the longshore current, are of interest to nearshore research because they can act as a cross-shore mixing mechanism for the current. The best method to study them is in a controlled environment, such as circular wave tank where continuous longshore currents can be generated....
