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-

No Longer Just a Hole in the Ground The Adaptive Re
2013-12-15 A quarry is an area from which rocks such as marble, limestone, and granite are extracted for industrial use. Once depleted of their desired resources, quarries are frequently abandoned. The resulting gaping holes can fill with water and form dangerous quarry lakes while others are turned into unsightly landfills.
