APPENDIX C METHODS FOR RIPRAP DESIGN

2010-12-1  METHODS FOR RIPRAP DESIGN Sizing riprap is complicated by the wide range of variability in river channel characteristics. Because of this variability, designers often resort to simple equations and nomographs. Typically these methods use an average water velocity as the main criterion. There are limitations with this approach. A velocity-
