## Abstract An implicit method is developed for solving the complete threeβdimensional (3D) NavierβStokes equations. The algorithm is based upon a staggered finite difference CrankβNicholson scheme on a Cartesian grid. A new topβlayer pressure treatment and a partial cell bottom treatment are intro

## Abstract The hydrostatic pressure assumption has been widely used in studying water movements in rivers, lakes, estuaries, and oceans. While this assumption is valid in many cases and has been successfully used in numerous studies, there are many cases where this assumption is questionable. This
In this paper a semi-implicit finite difference model for non-hydrostatic, free-surface flows is analyzed and discussed. It is shown that the present algorithm is generally more accurate than recently developed models for quasi-hydrostatic flows. The governing equations are the free-surface Navier -
