Mathematical Modelling of 3D Coastal Morphology

The present lecture deals with models for situations in which the spatial dimensions cannot be separated according to the scales of the morphological processes. Rather common examples of such situations are the morphological evolution near structures (e.g, breakwaters), river outflows, tidal inlets, etc. But also in the absence of such distinct...

Modeling of channel patterns in short tidal basins

We model branching channel patterns in short tidal basins with two methods. A theoretical stability analysis leads to a relationship between the number of channels and physical parameters of the tidal system. The analysis reveals that width and spacing of the channels should decrease as the slope of the bottom profile and the Shields parameter...

A process-based approach to sediment transport in the Yangtze estuary

A process-based model for the Yangtze Estuary is constructed to study the sediment transport in the estuary. The proposed model covers the entire tidal region of the estuary, the Hangzhou Bay and a large part of the adjacent sea. The dominant processes, fluvial and tidal, are included in the model. The calibration of the model against extensive...
