Validating wind field models for storm surge simulation in semi-enclosed seas
Accurate typhoon wind fields are the foundation of credible storm surge simulation, yet their performance in semi-enclosed seas like the Bohai and Yellow Seas has remained largely unvalidated. This study puts three parametric models and four blending methods to the test, using a coupled SWAN-ADCIRC framework against real typhoon data. The results are sobering: no single configuration dominates across wind, wave, and surge variables. Spatial structure matters more than peak wind speed alone.
Pipeline Integrity at Risk: Understanding Vibration and Scour in Unsteady Flows
A suspended pipeline on an erodible bed does not fail all at once; it fails through a quiet accumulation of vibration and scour, each cycle eroding the margins of safety. Our experimental work shows that the clearance ratio, not just the flow rate, governs this process. As \( e_0/D \) crosses from 0.8 to 1.2, the cross-flow amplitude surges by 76% while the in-line response lags, revealing a partial decoupling that challenges steady-flow assumptions. This selective amplification, coupled with a frequency lock near 2.
Dynamic Ocean Data Refines Extreme Sea Level Projections for Western Europe
Future changes in extreme still water levels cannot be understood through sea-level rise alone. Our dynamic modeling reveals that tides, storm surges, and seasonal cycles will reshape coastal flood risk across western Europe, with regional deviations reaching ±20 cm. Static approaches miss these complexities. In the southern North Sea, dynamic estimates amplify projections by 30-40%.
