Design of riprap revetment hec 11
WebJan 4, 2016 · Spread a representative, well-mixed sample of riprap to form a flat, rectangular pile. The thickness of the pile should be approximately equal to the D100. The length and width of the footprint should be determined based on the rock size and the minimum sample size that is requested by the Engineer. 2. Webexception of riprap aprons. Refer to ion 11.6 Sect when designing riprap aprons. This Chapter provides a brief overview on energy dissipators and references HEC 14 for detailed design. With the exception of riprap aprons, the HEC 14 design methods have been automated in the FHWA software HY-8; see Chapter 18 “Hydraulic Software.”
