A DISCUSSION OF THE RESULTS OF SOME LABORATORY TESTS ON BREAKWATER ARMOUR UNITS

During 1969-70 some laboratory tests were completed for the Department of Public Works at Laval University, Quebec City. The aim of the program was to compare the efficiency of Dolos, Tetrapod and quarry stone armour units. A model breakwater was constructed to a linear scale of 1:16 and tests were completed with regular and irregular waves. The results of these tests are discussed and comments are made on the implications of graphs showing incident wave height versus damage curves in standard design procedures for rubble mound breakwaters, particularly in depths of less than 40 feet or so. A review of the literature describing similar tests suggests that there is a need for agreement on the definition of damage and on some uniformity of data presentation. The effect of storm duration, the stability of units on the breakwater facing and the need for control during placing of the units is discussed.
