| Abstract: |
In this paper we present a new vertical approximation of the non-hydrostatic pressure based on a Box method. It makes it possible to take into account the effect of the non-hydrostatic pressure with a very small number of layers (1–3). Also for a one layer depth-averaged model the results improve and are for short free surface waves comparable with a Boussinesq type of model. For stratified flows the number of layers is dependent on the vertical density gradients and the method presented here is less efficient. The stratified case needs further research. |
