Bridges reshape seabed evolution through measurable sediment transport disruptions
A sea-crossing bridge is not a passive structure. The Zhoudai Bridge measurably reshapes seabed evolution by disrupting sediment transport in the Zhoushan sea area. Our hydrodynamic model, validated against field data, shows localized tidal drawdown and a 0.08 m/s velocity increase in navigation spans. These piers enhance suspended sediment transport, with deposition accumulating distally over time. Understanding these calibrated disruptions is essential for integrated coastal infrastructure planning.
Validating tidal current models for ODYSEA satellite ocean insights
Validating tidal current models for the ODYSEA satellite mission demands precision, and this study delivers it. MITgcm outputs were rigorously tested against 106 in-situ records from eight coastal regions, revealing mean RMSEs of 8.85 and 9.55 cm s⁻¹ for the dominant M2 and S2 constituents. While FES2022 shows smaller errors, MITgcm remains within the correct order of magnitude, proving its value for mission preparation.

Shamal Winds Reveal the Physical Drivers of Arabian Gulf Mixing
Cold, dry Shamal winds do more than chill the air; they reach down and stir the entire water column. New research from the northwestern Arabian Gulf shows that these winter events drive convective mixing all the way to the seabed, fundamentally reshaping turbulence in this shallow basin. The study's model, observation comparisons reveal a critical insight: tidal shear dominates under calm conditions, but Shamal peaks override that mechanism, homogenizing the water column and suppressing shear-driven mixing.
