Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Stability of Dolos and Tribar Overlays for Rehabilitation of Stone-Armored Rubble-Mound Breakwater and Jetty Trunks Subjected to Breaking Waves
It was concluded that: (1) Randomly placed dolos are an acceptable option, provided that a stability coefficient of 12 is used to size the units; (2) Dolos stability proved to be sensitive to relative depth (d/L) and relative wave height (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; (3) Randomly placed tribars are not recommended at slopes steeper than IV on 2H; however, they may be used at milder slopes with a stability coefficient of 9; (4) Uniformly placed tribars are an acceptable option for a IV-on-1.5H slope, provided they are used in concert with toe buttressing stone, size selections is based on a stability coefficients of 7, and placement of the units replicates that used in the model; (5) Tribar stability appears to be insensitive to d/L and H/d for both types of placement.
