Seawall Protection Structure, Great Highway

San Francisco, CA

NCI conducted a physical hydraulic model study as part of the Ocean Beach concrete seawall design. Components of the seawall included a sheet pile cut-off wall, a wave rundown dispersion bench, a sloping stepped section, a wave runup dispersion bench, and a recurved wall. The hydraulic model investigation was utilized to determine dimensions and shape of the wall for the purpose of minimizing potential wave overtopping and beach scour. In addition, hydraulic loads on the wall were determined. The tests were conducted in a wave flume at the University of Florida using an undistorted scale of 1:10. Tests were conducted for variations in structural shape, beach elevations, stillwater levels, wave heights and wave periods. For beach scour tests, the sand was modelled following Lepetit and Leroy.
