Physics-Guided Spatiotemporal Learning for Coastal Wave Peak Period Estimation from Video
Summary
A new Physics-Guided Deep Spatiotemporal Learning Framework is proposed for directly estimating nearshore wave peak periods from passive coastal video streams. This framework addresses the high costs and limited spatial coverage of traditional monitoring systems like buoys and radar. It integrates automated temporal-variance based region-of-interest detection, multi-stage Sim-to-Real transfer learning, and physics-informed regularization to improve predictive accuracy and physical consistency. The study assessed transformer-based and recurrent-convolutional architectures, finding transformers offered higher instantaneous prediction accuracy, while recurrent-convolutional models achieved greater temporal stability and operational oceanographic skill. Ablation studies confirmed physics-guided regularization enhances trend-following consistency and reduces implausible predictions. Explainability auditing further validated the framework's focus on active surf-zone regions, aligning with physical wave propagation. The system shows promise for cost-efficient, operationally feasible long-term coastal wave monitoring.
Key takeaway
For coastal engineers and marine hazard assessors evaluating wave monitoring solutions, this physics-guided video-based deep learning framework offers a cost-efficient and operationally feasible alternative to traditional systems. You should consider integrating such spatiotemporal learning approaches, particularly those with physics-informed regularization, to achieve accurate and physically consistent nearshore wave peak period estimations for long-term coastal management and climate resilience efforts.
