Riprap Revetment Design
PURPOSE: To present a method and procedure for designing uniform-stone and graded-stone revetments for protection against wave attack. GENERAL: Revetments are used to protect ocean, estuary, and lake shorelines from wave attack. Because of increased construction in many coastal areas, some additional revetments may be needed along higher valued exposed embankments. For many of these revetments quarrystone is a common building material because it is often locally available, relatively inexpensive, and does not require complex construction techniques. On projects with a high degree of public access, minimum stone size of between 400 and 500 lb may be required to prevent vandalism. A sound approach to the design of a revetment structure for a particular site requires a careful study of existing structures in the area with similar wave exposure in order to evaluate the design in relation to the present condition. 'lllese data, along with presently available empirical formulae, are then used for design of the revetment. Since the wave attack on a revetment is directly related to the high and low tides as well as the design evel (SWL), these must be determined in order to find which type of wave (nonbreaking, breaking, or broken) the revetment will encounter. In many cases no comparable structures exist in the proximity of the study area, or those of a similar revetment design may have completely different wave exposure and are thus of limited value for comparison. 'llle following example illustrates a design procedure using presently available formulas for the design of a riprap revetment. For guidance on riprap channel protection, see ETL 1110-2-120 (Headquarters, Department of the Army 1971).
