Refining Wave Tank Data to Validate Boulder Transport Models
Coastal boulder deposits are powerful evidence of extreme wave activity, but interpreting them quantitatively has been limited by poorly constrained force-balance parameters. New analysis of controlled wave-tank experiments reveals that boulder shape and wave impact regime exert first-order controls on transport. Drag and friction coefficients remain robust across most cases, yet the inertia coefficient shows strong sensitivity to model structure. Elongated boulders require drag coefficients roughly 50% lower than cubic clasts.
ENSO Impacts Guangdong's Coastal Wave Exposure: A Longitudinal Assessment
Understanding drives protection. This longitudinal assessment of ENSO's influence on typhoon-generated wave exposure along Guangdong's coast delivers precisely the kind of empirical clarity coastal planners need. By integrating 46 years of ERA5 data with TC records and ONI indices, the study reveals a clear scale-dependent relationship: ENSO conditions meaningfully shape annual patterns of cumulative wave exposure, yet exert limited influence on individual event severity. This distinction is critical, ENSO offers valuable climatic context for seasonal preparedness, not deterministic forecasting.
