THE RELATIONSHIP BETWEEN WAVE LENGTH AND WEIGHT OF ARMOUR BLOCKS

Kuo-Quan Chen, Ruey-Chy Kao, Frederick L.W. Tang

Abstract


Every coastal engineer realizes that the weight of armour blocks decided by Hudson's formula is safe enough for short steep waves, however, suffering damage from long period swells, even though the incidental wave height is the same. Several corrections have been made and submitted to ICCE as well as in other occasion. The authors try to explain analytically the influence of wave length on the design weight of armour blocks and justify by much of experiments in order to offer new formula and graphs for practical application.
