An experimental model investigation was conducted to obtain design guidance for doles overlays used to rehabilitate tribar-armored rubble-mound breakwater and jetty trunks subject to breaking waves. It was concluded that a. The stability coefficient is independent of sea-side structure slope for slopes of IV on 1.5H and lV on 2H. b. Stability showed some dependency on both dL and Hd with minimum stability occurring at the lower values of dL and higher values of Hd, i.e. longer wave periods in shallower water. c. The minimum stability coefficient observed significantly exceeds that obtained for new construction.
