Abstract
Determination of causes affecting sedimentation is very important in oceanography. This study investigates mean annual sediment transport in Bolkheir port (and surrounding ports, Ameri and Rostami ports) after breakwater construction through modeling by Mike21 software. Results of this study show that construction of new breakwater and situation of Bolkheir port location (between two other ports) affect the sediment transport so that successive erosion and sedimentation frequentely occur in region between ports. Also two-dimensional sediment transport model shows gross cumulative rate of sediment transport. Rate of sediment transport in northern coast is about 5000 m3 /yr and in the southern coast is about 7000 m3 /yr . The annual rate of coastal sediment is 500 in backside of west arm of breakwater which is a meaningful amount of sediment.
