Web2000 A quantitative theory is described for the formation mechanism of sand bars under surface water waves. By assuming that the slopes of waves and bars are comparably gentle and sediment motion is dominated by the bedload, an approximate evolution equation for bar height is derived.

WebJun 23, 2024 · A 2D RANS-VOF model is used to simulate the flow and sand transport for two different full-scale laboratory experiments: i) non-breaking waves over a horizontal sand bed (Schretlen et al., 2011) and ii) plunging breaking waves over a barred mobile bed profile (Van der Zanden et al., 2016). WebWaves in a lake have a much shorter wavelength then the waves in open ocean under the same wind conditions because of the boundary conditions on all sides. The first layer of sand is a liquid mixture of sand and water which will be much denser than water, that is why in the picture the wavelength is so short with respect to the waves that ...
