Abstract : A hydraulic model investigation was conducted using a three-dimensional stability model at an undistorted linear scale of 1:36 (model to prototype). The purpose of the stability tests was to develop a random-placed armor-stone design for a proposed offshore breakwater (to be located seaward of the existing north jetty and middle jetty at Mission Bay, California) that will be stable for nonbreaking wave heights up to and including 16.7 ft at still-water levels of 0.0 and +5.4 ft mllw. Test results indicated that two alternative plans would be adequate for the nonbreaking wave conditions. One plan consisted of two layers of 29,000-lb stone random-placed on 1V-on-2H slopes on the breakwater heads and two layers of 22,700-lb stone random-placed on the 1V-on-2H ocean-side slopes and teh 1V-on-1.5H channel-side slopes of the breakwater trunks. The other plan consisted of two layers of 29,000-lb stone random-placed on the 1V-on-2H to 1V-on-1.5H slopes on the breakwater heads, random-placed on the 1V-on-2H to 1V-on-1.5H slopes on the breakwater heads, the 1V-on-1.5H ocean-side slopes, and the 1V-on-1.25H channel-side slopes.
