Flow Slide Diversion Walls
These slides show a method of reducing the hazard to structures below hillsides in areas where debris flows occur, by constructing walls that divert the flow slides around the structures.
This drawing shows the flow slide diversion wall concept. The V-shaped upper end is designed to divert the flows to either side of the structure. (Drawing by Hollingsworth and Kovacs).
