Risk-informed asset management to tackle scouring on bridges across transport networks

Scour is one of the main causes bridge failures resulting in significant macro-economic impacts, often beyond direct costs infrastructure damage. Given pressure to increase resilience transport networks, ageing infrastructure, constrained budgets, variable knowledge asset conditions and limited data, mixed ownership operation bridges, concerns about risks climate change, there a need implement cost-effective monitoring maintenance strategies. To this end, study aims set scene for risk-informed approach tackling scour, while considering socio-economic impacts disruptions due or closures. This reviews current practices predicting, managing scour. It discusses development aid whole-life appraisal bridges indirect associated with failure The provides rational means enable managers evaluate factors that affect risk, select prioritise appropriate mitigation measures, thereby improving allocation scarce resources.
