Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Stability of Dolos-Armored Rubble-Mound Breakwater and Jetty Trunks Subjected to Breaking Waves.

Abstract

An experimental model investigation was conducted to obtain design produce for dolos overlays used to rehabilitate dolos-armored rubble-mound breakwater and jetty trunks subjected to breaking waves. All tests were conducted with a 1V-on-10H slope fronting the test sections and 1V- on-1.5H- and 1V- on-2H-structure slopes. It was concluded that: a) Stability showed some dependency on 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 b) The minimum stability coefficient observed is very similar to that presently recommended for new construction (15.6 versus 15). Keywords: Armor units; Breakwaters; Jetties; Rubble mound; Dolos.
