Abstract

The wide range of complexities involved in the processes of scour and channel instability at bridges have limited the ability to mathematically or physically model these processes. The additional complexity of mitigation structures at bridges and other unique features further limits the use of existing models. In order to consider the processes and interactions of contraction scour, local scour, meander migration, bank instability, bed degradation, and mitigation measures, a systematic method is needed to examine consequences of the various processes and interactions. Fault tree analysis is a systematic method of identifying faults and their interactions in a complex system. In this paper, the use of fault tree analysis to determine critical paths to failure and to calculate the probability of failure due to both scour and channel instability is demonstrated.
