Abstract: A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located in Prudhoe Bay, Alaska, in a water depth of 8 feet. The physical model studied armor stability, slope stability, wave run-up, and wave overtopping. Measured values of monochromatic wave run-up and overtopping were compared to those computed using standard prediction methods. Computed wave run-up and overtopping values substantially exceeded the values measured in the model study. Further analysis shows that overtopping prediction is improved if large-scale run-up data is used as input to the wave overtopping equation.
