Backshore sill beach and dune erosion control system
A backshore sill beach and dune erosion control system is described comprising: a supporting protective apron formed of weather and water resistant cloth. The apron includes a flat base portion and an angularly sloped portion extending seaward of the base portion, a toe scour anchor tube connected to the seaward end of the apron sloped portion, and longitudinal sand-filled geotextile containers placed upon the apron base portion each extending longitudinally shore parallel to the incoming surf. The sand-filled geotextile containers are specifically placed upon the beach in a pyramidal longitudinally extending shore parallel relation to an area being protected whereby wave action impacts upon relatively soft surfaces of the containers and is dissipated before normally impacting surfaces that would otherwise be eroded.
