A study of the applicability and design of spur-type flow-control and streambank stabilization structures has been conducted to establish design guidelines and other criteria for the use of spurs. The recommendations and findings are based on a thorough review of pertinent literature, analysis of several hundred field sites, and on a recent laboratory study conducted by the Federal Highway Administration. Recommendations for the general application of spur-type structures are given in relation to function of the spur, the erosion mechanisms that are countered by spurs, the environmental conditions best suited for the use of spurs, and potential negative impacts produced by spurs. An introduction to the most common types of spurs is given, along with discussions of the factors most important to the design of specific spur types. Design guidelines for establishing spur permeability, the required extent of protection, spur length, spur spacing, spur orientation, spur height, spur crest profile, and the shape of the spur tip or head are presented. An example outlining recommended procedure for establishing the geometric layout of spurs within a spur scheme is recommended.
