A rock armour revetment reduces toe scour compared with a vertical wall because it
Answer: C
Correct answer: dissipates rather than reflects much of the incident energy
A rough, permeable slope breaks the wave and lets water percolate into the armour, turning much of the energy into turbulence and friction within the layer. A vertical face returns most of it seaward, and it is that reflected energy, interacting with the incoming waves, that sets up the scouring flow at the toe. Less reflection means less scour, which is the principal hydraulic argument for a sloping revetment.
