Lyn, D. A., & Newton, J. F. (2015). Approaches to the design of biotechnical streambank stabilization: Volume I—A guide to the literature (Joint Transportation Research Program Publication No. FHWA/IN/JTRP-2015/14). West Lafayette, IN: Purdue University. http://dx.doi.org/10.5703/1288284315998
Streambank stabilization has traditionally been performed with riprap for which reliable design and installation procedures are available. Due to concerns about the environmental impact of riprap, there has been increasing interest in more natural biotechnical (or bioengineering) alternatives. A review of the literature on biotechnical approaches to streambank stabilization has been performed, with a focus on those works that might be particularly useful in developing design guidelines or standards for the Indiana Department of Transportation. Works that synthesized the literature (up to about the year 2000) and so covered a broad range of topics, were examined, including monographs and manuals published by federal and state agencies. More recent publications were also found on narrower more specific topics, including the ecological effects of riprap and biotechnical approaches, advances in the geotechnical modeling of vegetation effects on bank stability, the effectiveness of biotechnical measures, and screening methods for selecting appropriate measures. Implications of the reviewed work for the development of design guidelines are discussed.
