The response of a sand beach was measured for various water levels and wave heights, both with and without an upper cobble berm. During the experiment, the dynamic revetment demonstrated dynamic stability, as the individual cobbles within the structure moved with every wave but the global shape of the revetment remained stable.

[37] Beach profiling is a very accurate source of information. However, measurements are generally subject to the limitations of conventional surveying techniques.
