  • Evaluation of ocean wave-induced liquefaction in a large scale wave flume

    Creator:
    Thielen, David Leo
    Abstract:
    Ocean waves propagating over cohesionless seabed deposits produce cyclic shear stresses within the deposit. Under certain conditions these stresses may cause a progressive build-up of pore pressure. Pore pressure accumulation can result in liquefaction or a substantial decrease in the effective stress with attendant large deformations of the seabed deposit....

  • On the nearshore impact of wave energy converter arrays

    Creator:
    O'Dea, Annika Magnuson
    Abstract:
    Radiation stresses, defined as the excess flow of momentum due to the presence of waves (Longuet-Higgins, 1964), are the main drivers behind the cross-shore and longshore forcing that results in wave setup, set-down, and longshore currents (e.g. Svendsen, 2006). Longshore currents entrain and transport sediment and therefore play an important...

  • Analysis of waves in the near-field of wave energy converter arrays through image processing

    Creator:
    Black, Colleen
    Abstract:
    Oregon State University conducted a series of laboratory experiments to measure and quantify the near-field wave effects caused within arrays of Wave Energy Converters (WEC). As the waves and WECs interact, the WECs generate radiated waves; these effects vary with the location within the array. Analyzing the near-field waves will...

  • Wave field patterns generated by wave energy converters

    Creator:
    McNatt, J. Cameron
    Abstract:
    The eventual deployment of wave energy converters (WECs) on a commercial scale will necessitate the grouping of devices into arrays or "wave farms," in order to minimize overhead costs of mooring, maintenance, installation, and electrical cabling for shoreward power delivery. Closely spaced WECs will interact hydrodynamically through diffracted and radiated...

  • Wave interaction with permeable structures

    Creator:
    Lee, Chung-pan
    Abstract:
    A theory is developed to provide an analytical solution to an unsteady flow field which is partially occupied by a porous structure. The flow is induced by a small amplitude incident wave train. The porous structure may contain multi-layer anisotropic but homogeneous media. Three typical porous structures are investigated: a...

  • Wave-current interaction induced by standing long waves in the surf zone

    Creator:
    Phaksopa, Jitraporn
    Abstract:
    This dissertation has focused on the charateristics of bubbles generated by breaking waves and the feedback of wave-current interaction on the forcing mechanism of low frequency wave especially basin seiching wave. For the first study, Optical image capture observations of breaking waves in a laboratory surf zone are presented. The...

  • On the Imaging of Rip Currents in X-band Radar

    Creator:
    Kloster, Rebecca
    Abstract:
    Rip currents pose a serious danger to visitors of bathing beaches; they are also an important process in surf zone circulation. Haller et al. [2014] demonstrated that shore-based X-band radar can be used to compliment in situ measurements of rip currents. However, little is known of the underlying radar imaging...
