Modelling of Sediment Transport in Beris Fishery Port

In this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of beris fishery port are studied. a series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. the outputs show that the nearshore directions of wave components are not perpendicular to the coast which reveals the existence of longshore currents and consequently sediment transport along the bay. considering the dynamic equilibrium condition of the bay, the effect of the existing sediment resources in the studied area is also investigated. the study also shows that in spite of the change of the diffraction point of beris bay after the construction of the fishery port, the bay is approaching its dynamic equilibrium condition, and the shoreline advancement behind secondary breakwater will stop before blocking the entrance of the port. the probable solutions to overcome the sedimentation problem at the main breakwater are also discussed.
