Dolos armor units used on rubble-mound breakwater trunks subjected to nonbreaking waves with no overtopping : final report

This investigation describes a portion of a research effort to provide fundamental data for the design of rubble-mound breakwaters. This report addresses the use of dolos armor on breakwater trunks subjected to nonbreaking waves and with no overtopping. The majority of the tests reported herein were designed to determine the stability coefficient, K, and runup and rundown values for the above conditions. Additional limited tests were conducted to show what effects (1) varying the first underlayer stone material from 1/5 to 1/20 of the armor weight (Wr) would have on armor stability, wave runup, and wave rundown; (2) placing the dolosse in selected geometric patterns would have on stability; and (3) reducing the number of dolosse used in the cover layer would have on stability.
