Stability of Proposed Breakwater, Burns Waterway Harbor, Indiana. Hydraulic Model Investigation.
Abstract
Six series of tests were conducted on 1:35-scale models of the proposed rubble-mound breakwater. Five test series were conducted to develop stable designs for rubble-mound type breakwaters constructed of armor layers consisting of molded tribars (test series 1) or limestone blocks (test series 2-5). The sixth series of tests was concerned with determination of the experimental shape coefficient, voids, and thickness of a cover layer consisting of two layers of random-placed limestone blocks. The principal objectives of test series 1-5 were (a) to develop a stable design that would not be unusually difficult to construct, and at the same time would make optimum use of the different sizes of stone available from the quarry; and (b) to determine the heights of waves on the harborside of the breakwater resulting from the transmission of wave energy through and over the structure. A stable design using an armor layer consisting of two layers of random-placed limestone blocks was developed for the trunk section of the proposed rubble-mound breakwater based on a design-wave height of 13 ft.
