This report provides guidance for incorporating environmental considerations into streambank protection projects. The stability of the streambanks of a channel is related to both site-specific and basinwide stream reach factors. Streambank erosion or failure is a natural fluvial process that is often accelerated by changes in geotechnical or hydraulic factors and especially the activities of man, e.g., reservoir construction or land use change. Streambank protection projects stabilize the streambank, preventing or stopping erosion, mental changes. Stabilization results in a range of environ- An information review was performed to identify environmental features for streambank protection projects. Environmental features are those planning, design, construction, and maintenance procedures or practices that minimize adverse environmental impacts or enhance terrestrial and aquatic habitats and the aesthetic quality of land and water associated with streambank protection projects. Such features include structural and nonstructural designs; construction procedures that are environmentally compatible; maintenance procedures; and institutional, planning, and management approaches for streambank protection projects.
Each feature is discussed in terms of concept, the purpose or appropriate use of the feature, environmental considerations, limitations to use of the feature, performance history, and cost.
