Design standards No. 13 : Embankment Dams. Chapter 7 - Riprap Slope Protection

The upstream slopes of embankment dams and dikes typically require protection against the damaging effects of wave action, surface runoff, weathering, ice, and floating debris. This standard presents guidelines for site-specific design ofriprap slope protection subject to wave action only. It also presents a discussion of the major ,considerations and procedures for design and construction of riprap slope protection to achieve acceptable performance consistent with reasonable construction and maintenance costs. Criteria and procedures are presented for developing wind and reservoir operation data significant to riprap design, and evaluating the impact of other factors on the design. Procedures for determining adequate riprap sizes, gradation, and bedding requirements are described. Methods and/or requirements for designing other types of slope protection, such as soil cement, and riprap for stilling basins and channels are not detailed in this design standard.
