Numerical models for coastal ocean current are usually based on several simplifications like hydrostatic approximation and Boussinesq approximation, and hence it is required to examine the influence of these simplifications on the coastal current simulation. In the present study, the effect of the hydrostatic approximation for fluid motion in the vertical direction on 3-D river jet are studied using coastal current models with and without hydrostatic approximation. The computational results show that the introduction of the hydrostatic approximation into the numerical models affects appreciably the computed 3-D features of the front. Furthermore, the momentum budget for vertical motion is also examined to clarify a momentum balance near the front.
