  • Field observations of the wave bottom boundary layer

    Creator:
    Foster, D. L., Beach, R. A., and Holman, Robert A.
    Abstract:
    This paper presents a comprehensive set of velocity and suspended sediment observations in the nearshore wave bottom boundary layer, collected during the Duck94 field experiment on the Outer Banks of the North Carolina coast. Cross-shore velocity measurements in the wave bottom boundary layer were made using five hot film anemometers,...

  • Turbulence observations of the nearshore wave bottom boundary layer

    Creator:
    Foster, D. L., Beach, R. A., and Holman, Robert A.
    Abstract:
    Field observations of turbulence and sediment suspension in the nearshore wave bottom boundary layer obtained during the Duck94 field experiment on the North Caroline coast showed the generation of near-bed turbulence to be highly intermittent. The intermittent nature of the flow was examined by applying homogeneous isotropic turbulence laws over...

  • Rip spacing and persistence on an embayed beach

    Creator:
    Holman, Robert A., Symonds, G., Thornton, E. B., and Ranasinghe, R.
    Abstract:
    Four years of daily time exposure images from an embayed beach were examined to study the spacing, persistence, and location preferences of rips in a natural rip channel system. A total of 5271 rip channels was observed on 782 days. Occurrence statistics showed no evidence of the preferred location pattern...

  • Wave run-up on a high-energy dissipative beach

    Creator:
    Ruggiero, Peter, Holman, Robert A., and Beach, R. A.
    Abstract:
    Because of highly dissipative conditions and strong alongshore gradients in foreshore beach morphology, wave run-up data collected along the central Oregon coast during February 1996 stand in contrast to run-up data currently available in the literature. During a single data run lasting approximately 90 min, the significant vertical run-up elevation...

  • Runup kinematics on a natural beach

    Creator:
    Holland, K. T., Raubenheimer, B., Guza, R. T., and Holman, Robert A.
    Abstract:
    Runup kinematics on a gently sloping natural beach are examined with detailed measurements from video images, resistance wires deployed at five elevations (between 5 and 25 cm) above and parallel to the beach face, and pressure sensors located in the inner surf zone. As suggested in a previous study comparing...

  • Swash zone sediment suspension and transport and the importance of bore-generated turbulence

    Creator:
    Puleo, J. A., Beach, R. A., Holman, Robert A., and Allen, J. S.
    Abstract:
    A study of swash zone sediment transport was conducted at Gleneden Beach, Oregon during February 25-28, 1994. The data collected included suspended sediment concentration (SSC), sea surface elevation, and velocity (initially 4 and 8 cm above the bed) at three cross-shore locations within the swash zone spanning high tides. Ensemble...
