Abstract:Natural cobble or gravel berm beaches have long been observed to be generally more stable than sand beaches. This has led them to be used as an alternative approach to shore protection. This type of shoreline protection has been referred to as a, dynamic revetment, or cobble berm. Since this type of shoreline occurs naturally, in some settings it could be more aesthetically and environmentally acceptable than riprap. Depending on the proximity of materials, dynamic revetments are potentially less expensive to construct than riprap armoring. Since they are dynamic features, they can absorb more of the wave energy rather than reflecting much of it the way riprap does. This mitigates some of the functional problems associated with riprap.
