Reference Guide for Applying Risk and Reliability-Based Approaches for Bridge Scour Prediction
This report presents a reference guide to identify and evaluate the uncertainties associated with bridge scour prediction including hydrologic, hydraulic, and model/equation uncertainty. Tables of probability values to estimate scour depth with a conditional probability of exceedance when a bridge meets certain criteria for hydrologic uncertainty, bridge size, and pier size are included in the reference guide. For complex foundation systems and channel conditions, a step-by-step procedure is presented to provide scour factors for site-specific conditions. The reference guide also includes a set of detailed illustrative examples to demonstrate the full range of applicability of the procedures. The report will be of immediate interest to hydraulic and bridge engineers.
