This report is a reference guide for analyzing the risks associated with bridge scour predictions. The areas studied included hydraulic, hydrologic, and uncertainties inherent in the models. Step-by-step procedure are listed for complex foundation systems and systems in channel conditions to assess scour factors. Tables of probabilities for various underlying conditions are included. The report is a technical report of interest primarily to engineers.
