Climate-related disasters have cost the world more than £450 billion over the last three years. Transport infrastructure is directly impacted by climate change with extreme weather conditions accounting for up to 35% of delays/service interruptions in road and rail infrastructure. One such event was the 2009 floods which resulted in the partial or total collapse of 29 bridges in Cumbria. The probability of repeated events in the future is extremely high given that 40% of UK bridges are considered historic assets (that is, beyond their design life) and the majority of our bridges possess similar attributes, in terms of age, construction type and condition, as those identified in the Cumbria failures.
Compared to development of low carbon emission technologies the adaption of existing infrastructure to increase its ability to absorb and recover the effects of climate change is relatively unexplored. Current studies focus on the short-term impacts, fail to consider the interdependency of predicted climate events with factors such as bridge condition, age, maintenance and limited redundancy, and consequently cannot accurately identify true vulnerabilities. This PhD will use the 6000 bridges within the Northern Ireland road network as a research platform and build on the supervisor’s current research in relation to predictive maintenance of bridges to:
Prepare transport networks for climate risk by first developing a framework which would facilitate statistical analysis of climatic and environmental controls on bridge condition at network level.
Predict the vulnerabilities based on inspection records and future climate prediction models using statistical data analytics and machine learning models to inform a scenario-based approach to establish the risks in terms of likelihood of occurrence, timeframe of event, consequence and resilience of the infrastructure to absorb it.
Adapt bridges within transport infrastructure using robust decision-making methodology to minimise long-term risk by identifying potential adaption measures to integrate with future maintenance programs.
The PhD will be based in the School of Natural and Built Environment, Queen’s University Belfast. You will be supervised by Dr Myra Lydon (a Royal Academy of Engineering Research Fellow), Professor Adele Marshall (Professor of Statistics, School of Mathematics and Physics, QUB) Professor Su Taylor( Professor of Structural Engineering, QUB)
University of Cambridge). The student will join the existing research team at QUB and work closely with the supervisors and The Northern Ireland Department for Infrastructure.
