Resumen:

This paper presents the results of an experimental investigation performed to understand the occurrence of scour in front of a vertical seawall. A single wave steepened by an artificial slope that breaks on the seawall or as close as possible to it was generated. For this purpose, a physical model was constructed and placed in a 2D wave flume where a focused wave group was generated at the toe of the fore slope. Three distinctive sediment types for the slope were tested (sand and two gravel sizes) and the experimental program included tests with different slope angles, relative submergence, still water depths and energy spectra (Jonswap and Top-Hat). Empirical models for the prediction of scour as a function of the maximum wave height at toe of the slope were obtained for the sand and smallest gravel slopes. © 2017 American Society of Civil Engineers.
