Application of reliability analysis to hydraulic engineering covers a wide scope of subfields, ranging from data collection and gaging network design to turbulence loading on structures. This state-of-the-art report surveys a sampling of current topics pertinent to the design and safety of hydraulic structures. Chapters examine recent progress in uncertainty and reliability analyses for hydraulic design and applications to dam safety, coastal floods, and hydraulic structures. Topics include confidence intervals of optimal risk-based hydraulic design parameters; probabilistic inspection scheduling for dams; and risk analysis for the selection of low water crossing structures.
