ANALYSIS OF COMMONLY USED RIPRAP DESIGN GUIDES BASED ON EXTENDED SHIELDS DIAGRAM

River and coastal engineers are often faced with the task of selecting the appropriate riprap size for bank protection. Several empirical formulae based on field and laboratory tests have been suggested for selecting the maximum size and gradation size distribution of the riprap. To facilitate riprap size selection, several commonly used riprap design guides presented by the U.S. Army Corps of Engineers (for shore protection), the U.S. Bureau of Reclamation (for bank protection), and the California Department of Transportation (for both shore and bank protection) as well as guides from projects sponsored by the FHWA (for energy dissipators related to both culverts and channels) are analyzed. It is found that all these design guides are compatible and agree with the extended Shields incipient motion diagram for large sediment sizes. (Author)
