In order to calculate accurately two dimensional water waves by finite differential method, it is demanded that parameters controlling calculated results should be selected suitably. This paper deals with the effects of numerical parameters controlling calculated wave profiles such as minimum spacing of grid, time increment and Reynolds number. Numerical computation by finite differential scheme was applied to the two dimensional wave problem generated by the moving pressure disturbance on water surface. The used computational cheme is similar to MAC method. The characteristics of this computational method are that the two dimensional Navier-Stokes equations are treated including viscosity terms, and the body fitted coordinate system and the staggered mesh system are adopted. As results, we could find these computational efficiency parameters.
