Web10.2.3 Riprap Outlet Basins . A riprap basin is a depressed area of riprap placed at the outlet of a high velocity culvert, storm drain outlet or open channel. The riprap reduces the exit velocity by expanding the flow over the riprap length and width and forming a hydraulic jump. For the design of riprap basins, refer to the VDOT Drainage Manual.
