Wind-generated waves in navigation pools Chamberlin, F. 1994. Wind-generated waves in navigation pools. Report by the U.S. Army Corps of Engineers, St. Paul, the National Biological Service, Environmental Management Technical Center, Onalaska, Wisconsin, December 1994. LTRMP 94-S001. 16 pp. (NTIS #PB95-209532) ABSTRACT As a habitat restoration measure, islands have been constructed in the shallow navigation pools of the Upper Mississippi River, St. Paul District. Part of the design assumption was that islands reduce wind fetch, dampen wave action, and alter current velocity in the vicinity of the islands. An evaluation of the effectiveness of islands on wave action would allow more informed planning and improved design for future island construction. This requires a knowledge of the wind-driven wave process and a method of wave forecasting. A literature review to determine the effects of wind speed, fetch length, and water depth on wind-driven wave heights was performed. Numerical models that predict wind-driven wave heights and perform wave transformations in shallow water were investigated. Based on the literature review, numerical models best suited for the study areas are identified. KEYWORDS adjusted wind speed, deep water, shallow water, radial fetch winds, refraction, defraction
