This course focuses on streambank stabilization techniques for both restoration and traditional flood control projects. Traditional "hard" structural-type channel bank stabilization techniques are discussed (using rock riprap, gabions, articulated concrete blocks) as well as re-directive techniques. Participants will learn the concepts of channel stability analysis, causes and characteristics of bank scour, how to recognize various types of tow failures, and how to perform assessments of vertical and lateral stability and understand their influence on toe scour. Course participants will also gain knowledge on evaluating various design methods, determining which toe protection method is applicable, and making recommendations for inspection and maintenance. In addition, the influence of channel bends on scour depth and length of protection and other toe design features are discussed. Pictures and discussions of both failed and successful streambank stabilization projects will be presented. The course also includes a video that documents the failure of a bank stabilization project in the northwest.
