Abstract:A summary off two reports resulting from a review of the applicability and usefulness of countermeasures used to stabilize eroding streambanks in the vicinity of roadways and at bridge crossings is given. The first report discusses erosion processes in channel bends and methods of controlling this erosion, identifies useful flow control and streambank stabilization structures, and provides guidelines for the selection of an appropriate flow control or streambank stabilization countermeasure for a particular field design condition. Some design information for specific countermeasure types is also included. The second report looks in detail at the applicability and design of spur-type-flow-control and streambank stabilization structures. The report alerts engineers to the utility of spurs, including economic and other advantages, and provides a treatment of the effectiveness and limitations of spur-type structuring. Design guidelines for these spur-type structures are developed based on field and laboratory experience.
