Taking for example the flow over a ripple, some results of a hydrodynamic numerical model are presented and compared with experimental results. Special importance is attached to the pressure. On the basis of the used equations the physical reason for the horizontal pressure gradient is investigated. The influence of some dune and flow parameters on the friction is examined.
