Generation of sand bars under surface waves

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 ...
