Abstract: This study proposes a satellite imagery (SI) -based approach to assess the risk of large wood (LW) accumulation at bridges, which can threaten structural integrity, exacerbate flooding, and increase scour risks at piers and abutments. The methodology quantifies the susceptibility of bridges to LW and identifies vulnerable bridges with the goal to inform mitigations to potential damage. Applied to rivers in Devon, UK, the study identified 26 bridges at risk, with the majority susceptible to LW jams. The results highlight the utility of SI as an efficient, cost-effective tool for the rapid assessment and planning of LW risk mitigation strategies, enabling timely interventions that enhance bridge resilience and reduce disruption to transport networks.
