ClearA wave-resolving two-dimensional vertical Lagrangian approach to model microplastic transport in nearshore waters based on TrackMPD 3.0
Researchers developed a wave-resolving model to simulate how microplastics move through nearshore waters, accounting for processes like resuspension from the seabed and turbulence-driven transport.
