Ship wave characteristics in a shallow and restricted waterway whose depth and breadth change in longitudinal direction are studied numerically. The Euler and continuity equations are employed for the present study. Boundary fitted and moving grid system is adopted in the numerical simulation. The convection term in the governing equations and the free surface boundary condition are solved by Cubic Interpolated Pseudo particle (CIP) algorithm in order to get high resolution of wave height in far field as well as near field. The present numerical scheme is applied to predict ship waves in shallow and restricted waterway whose depth and breadth vary in longitudinal direction.
