About this Research Topic
Scour has been considered worldwide as one of the deterioration mechanisms that pose the highest risk of bridge failure. Climate change may impact the frequency and intensity of flood events, therefore posing questions on how the risk of bridge failure due to scour may change over time. Whilst the academic community has been developing computational methods and frameworks for capturing climate change effects on scour risk, bridge owners and managers are actively seeking practical ways for utilizing such new developments for everyday management and operation of their assets, as well as whole-life risk assessment and planning.
A comprehensive assessment of the bridge scour problem involves a combination of several fields including hydrologic studies, hydraulic analyses, structural assessment, and risk management. There is a large number of existing older bridges around the world that may have not been designed to withstand current scour activity (e.g., having shallow foundations); the potentially harsher extreme events may have a detrimental effect on these structures. On the other hand, the design of new bridges with long service life needs to capture the potential effects of the changing climate conditions on scour risk over their life-cycle. Although the area of bridge scour has been well investigated in the literature, quantifying the potential effects of climate change on flood and scour risk of bridges is still limited. This Research Topic aims to cover the latest advances in capturing how climate change can affect the way we assess and manage scour risk in bridges, both existing and newly-built.
Areas to be covered in this Research Topic may include, but are not limited to the following:
• Life-cycle assessment of bridge scour considering climate change effects
• Reliability/probabilistic methods for bridge scour capturing the impact of climate change
• Multi-hazard risk and resilience analyses considering bridge scour and climate change
• Optimal decision-making against bridge scour under climate-related uncertainties
• Operational frameworks/protocols for managing extreme events due to bridge scour
• Climate change adaptation strategies for scour-critical bridges
• Risk assessment and management for bridge scour at stock and network levels
• Scour monitoring for life-cycle management
• Hydrologic/hydraulic studies for assessing climate change effects on scour
Keywords: bridge scour, climate change, risk, monitoring, probabilistic
