WAVE PRESSURE ATTENUATION IN BREAKWATER ARMOUR LAYERS

Kevin R. Hall

Abstract


An experimental investigation was conducted to examine the change in fluid pressure through a breakwater armour layer as a function of the incident wave characteristics, breakwater geometry, armour unit type, number of layers of armour and core permeability. Values of internal pressure were found to decrease with the number of layers of armour. The largest percentage decrease occurred within the first few layers; although this trend was somewhat influenced by armour type.
