Conceptual design of rubble mound breakwaters

The design tools given in this manual on rubble mound structures are based on tests of schematised structures. Structures in prototype may differ substantially from the test-sections. Results, based on design tools, can therefore only be used in a conceptual design. The confidence bands given for most formulas support the fact that reality may differ from the mean curve. It is advised to perform physical model investigations for detailed design of all important rubble mound structures.
