ABSTRACT
The design tools given in this chapter on rubble mound structure armour layers 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, which are given for most formulae, 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.
