MODELLING THE FLOW IN CURVED TIDAL CHANNELS AND RIVERS
River bends tidal channel bends Shallow flow Free surface flow Secondary flow Counter-rotating cell Negative eddy viscosity Mixing length Turbulence models RANS LES
2013/7/22
Flows in tidal channel bends and river bends are very shallow and mildly curved free surface flows. The shallowness and the curvature of the flow lead to a few flow features which are difficult to rep...

Based on triangle grids, a planar 2-D unsteady mathematical model of tidal flow is established by the finite element method in this article. Based on the model, a visual software is developed to proce...
MIXING AND DISPERSION IN TIDAL BORES: A REVIEW
Tidal bore Mixing and dispersion Sediment process Ecology Review
2013/7/22
When a river mouth has a flat converging shape and when the tidal range exceeds 6 to 9 m, the river may experience a tidal bore. A tidal bore is basically a positive surge propagating upstream as the ...
