Abstract: Shoreline and Coastal Protection and Rebuilding Apparatus and Method having a plurality of slanted wall sections in a rising stepped formation with open areas between, arrayed on frame structures, which dissipates wave energy in a gradual and controlled way and which neutralizes the impact of a wave and its backwash, thereby protecting the shoreline, and which allows for the settling of sediment, thereby rebuilding the shoreline, while allowing tidal exchange of water and the migration of aquatic species, using modular components that can be manufactured and deployed at low cost and in a manner suited to remote shoreline deployment.
