Abstract: The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction methods for these problems vary from rules of thumb, to empirically derived equations, to theoretically derived relationships. Recent studies at the U.S. Army Waterways Experiment Station's (WES) Coastal Engineering Research Center (CERC) indicate that sufficient design guidance exists for vertical walls, pipelines, and vertical piles, however, additional research is still needed for rubble-mound structures.
