Evolution of marine gravel dunes on the open shelf under multi-directional currents conditions

Frontiers in Earth Science, 2022
On inner continental shelves, a variety of coarse grained bedforms, such as gravel dunes, are shaped by hydrodynamic and morphodynamic processes. The formation and evolution of bedforms reflect a balance between seabed and coastal morphology, sediment ...
