Abstract. The theoretical background of a new finite-element non-hydrostatic model for simulation of free surface flows based on the fractional step method and pressure decomposition is presented. One of the verification cases concerning the solitary wave propagation is provided. Further developments concerning more sophisticated turbulence modelling for practical applications as flows around structures or scour formation are discussed and illustrated with preliminary, but very promising results.
