On inland waterways the ship resistance and propulsive characteristics are strictly related to the depth of the waterway, thus it is important to have an understanding of the influence of shallow water on ship motions to make inland vessels more economically competitive and reduce their fuel consumption, therefore accurate predictions of hydrodynamic forces in restricted waterway are required and important. This paper is aimed to predict ship resistance in shallow water by using commercial unsteady Reynolds– Averaged Navier – Stokes (RANS) solver. Volume of fluid (VOF) was applied for simulation of free surface flow around the ship. A comparison in the resistance on the hull is illustrated between shallow water and deep water. The numerical results obtained were validated against related experimental studies available in the literature.
