Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Stability of Dolos Overlays for Rehabilitation of Stone-Armored Rubble-Mound Breakwater Heads Subjected to Breaking Waves

Abstract

An experimental model investigation was conducted to obtain design guidance for dolos overlays used to rehabilitate stone-armored rubble-mound breakwater heads subjected to breaking waves. Based on model tests and prototype experience (Crescent City Harbor, and Humboldt Bay, California), the investigation concluded that: (1) Minimum stability was observed at 45-deg wave direction; (2) Stability proved to be sensitive to both d/L and H/d with minimum stability occurring at the lower values of d/L and higher values of H/d, i.e., longer wave periods in shallower water; and (3) The stability coefficient appears to decrease slightly as the armor slope becomes flatter.
