Abstract
 Considering a large number of beaches in the south and the north of the country, the issue of sedimentation in ports and erosion of beaches around the marine structures has great importance, and not paying attention to it can affect the efficiency of the port. One of the most important parameters in the detailed study of coastal sediment transport is the directional spreading of waves in this study by using Delft-3D software, the effect of directional spreading in the sediment transport is investigated. The results of this study show that wave height, changes in radiation stress gradient and flow velocity will change with a change in directional spreading. Simulation with a constant directional spreading coefficient reduces the accuracy of the results.
