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.
Crab Activity Impacts Sediment, Shaping Salt Marsh Resilience
Crabs are not just occupants of the salt marsh; they are architects of its edge. Our field experiment on Chongming Dongtan shows that crab herbivory suppresses creek-edge vegetation by more than half, and this loss of plant cover directly reduces sediment trapping. This top-down control is a critical, often overlooked, force in marsh resilience. Understanding this interaction is vital for predicting wetland survival against sea-level rise, a theme we also explore in our satellite framework for tracking coastal change.
