Scour Calculations Purpose Scour is one of the major causes of failure for stream and river projects. It is important to adequately as-sess and predict scour for any stream or river design. Designers of treatments such as barbs, revetments, or weirs (that are placed on or adjacent to streambeds) must estimate the probable maximum scour during the
