Project name:Real-Time Bridge Scour Detection for Structural Safety in Japan
This project develops a real-time method to estimate scour depth using vibration monitoring and eigenvalue analysis on a railway bridge pier model.
Bridge scour, caused by fast-flowing water eroding soil around foundations, poses a serious structural risk. Traditional scour detection methods are slow and ineffective under high river flow conditions.
By enabling continuous monitoring, this approach enhances early warning capabilities, improving bridge safety, stability, and disaster resilience in flood-prone areas.

Impact and Key Findings
1
A remote-sensing system with accelerometers was designed for real-time natural frequency measurement, ensuring continuous bridge pier stability monitoring even during swollen river conditions. This approach enhances structural safety by detecting scour-related vulnerabilities under challenging environments.
2
The system enables real-time, high-performance bridge safety assessment by detecting scour-induced vibration changes. It enhances early warning capabilities and maintenance strategies, strengthening the resilience of critical infrastructure against structural risks and environmental challenges.
3
Designed for scalability, the tool can integrate with smartphones, enhancing accessibility and cost-effectiveness. Its adaptability allows widespread use across diverse bridge types and locations, supporting real-time monitoring and improved infrastructure safety in various environments.
