In this paper, the flow pattern around the perpendicular and inclined groynes were simulated in three-dimensional using the Fluent software, which solves the flow equations using the finite volume method and cell-center scheme. The prismatic grids were used to descretize the computational domain. The perpendicular groyne was first investigated to verify the model results and the inclined groyne with to the flow direction was then considered. From the available turbulence models in the software, the two equation turbulence model was used in this research study. In order to include the free surface effect, the rigid-lid and volume of fluid schemes were used. The result of the latter scheme showed good agreement with the experimental results.
