Investigation of Tentative Model s of Sediment Transport at Lengeh Port

One of the important problems in ports is sedimentation in access channels and variations of coastline and sea bed, So that dredging for the optimal use of port has considerable price. One of the most important problems in coastal engineering is sediment transportation; because of some times the lack of residual materials show the existence of erosion in the region and in other points association of sediment indicates sedimentation. In this research at the first by comparing of Aerial imagery, coastline variations in Lengeh Port has been evaluated and then using LITPACK software related to DHI, using wave and current data and grading scales of sediments, coastline variation has been simulated and sedimentation in regional of study has been calculated. Results indicate that variation of coastline of Lengeh port in recent is very low and this condition is deposited in accordance with the sedimentary meager resources available in the region.
