Semi-implicit subgrid modelling of three-dimensional free-surface flows
In this paper, a semi-implicit numerical model for two- and three-dimensional free-surface flows will be formulated in such a fashion as to intrinsically account for subgrid bathymetric details. It will be shown that with the proposed subgrid approach the model accuracy can be substantially improved without increasing the corresponding computational effort.
