Abstract

This report describes reliability analysis undertaken on flood defences along the Dartford Creek to Gravesend Stretch of the Thames Estuary. This stretch comprises flood defences of varying types that are can potentially fail through different mechanisms. Fault trees have been constructed that identify the primary, historically observed, failure mechanisms associated with defence types. These fault trees have been used within the context of a reliability analysis. Some of the primary outputs from this analysis comprise annual probability of failure for each defence length and fragility curves for each defence length.
