Abstract:Transitions in flood defence structures are locations where a change occurs in the defence, whether in terms of internal or external geometry, construction or foundation materials or between flood defence segments. Such transitions can be viewed as falling into two major categories: Transitions consisting of spatial changes in the cross section of either the cover layer or the internal construction of a definable segment of a flood defence; Longitudinal transitions between flood defence segments of different types (e.g. between flood embankments and flood walls) or of different foundation conditions. In addition, if buried in flood embankments, objects such as conduits, culverts and pipes can form transitions of either type. The paper describes the content of a UK research project which has just commenced which is designed to: consider the presence of transitions during flood defence condition assessment; quantify the effects of transitions on defence performance (via fragility curves) and flood risk (via systems analysis); and manage the risk of transitions with improved design and retrofitted solutions for existing defences.
