Outfall and Structures

    These types of structures generally combine a retaining wall with wing walls and a scour protection apron often form part of a river wall protection scheme where drainage pipes discharge into water courses.

    The Rock-Netting may also be used only as scour apron protection to concrete outfall or inlet structures to provide erosion protection.

    Due to the nature of discharge of the outfall, consideration of the turbulent flow conditions occurring is required when determining the depth ot rock-netting protection.

    The design considerations are similar to those encountered in culvert and around bringe piers.
