This report provides guidelines for identifying, surveying, and accurately calculating dredging volumes for sand waves in navigation channels. Longitudinal and cross-channel surveying practices are evaluated and discussed as they pertain to sand waves. Volume calculation methodology is then presented in relation to sand wave dredging volume estimation. Conventional dredging methods and procedures are discussed as they pertain to sand wave dredging. Although conventional dredge types ar e effective at sand wave mitigation, inefficiency is a problem. The unique shape of sand waves in navigation channels has led to experimentation and development of innovative leveling techniques. These experiments and techniques are also described. Recognizing and understanding the sand wave problem in navigation channels establishes the need for a cost-effective specialized dredge or dredging technique. This report provides a basis for coupling continued sand waves research with dredging equipment designs while providing guidance to maximize the efficiency of current dredging practice.
