Coastal Sediment Transport, Engineering Practice,A case study in The Sea of Oman, Iran

There are many fishery ports in Iran. Sedimentation rate around these ports is one of the most significant parameters to design these small ports. It is usually difficult to estimate the longshore sediment transport (LST) with sufficient accuracy. Periodical bathymetric and beach profile measurements near the new harbours are a valuable tool for evaluating or calibrating the existent LST relationships and The final decision on the construction of the groin is made after monitoring the sedimentation rate around the port during the first few years after its construction. This paper discusses Coastal sediment transport in Zarabad Fishery Port Coastal area located in the Sea of Oman in Iran. sediment transport rates, derived from bulk sediment transport rate formulas (CERC and Kamphuis and Van Rijn) and measurements, were compared. Finally, Coastline changes due to construction of the port was simulated numerically by LITPACK. The model was calibrated using the periodically collected hydrographic data. The results showed that using bulk sediment transport formulas in the study area had errors of up to several times more than the real values and Coastline never reaches the tip of groin 20 years after construction of the port.
