چکیده مقاله:

Sediment deposition at the basin and the entrance of Noshahr Port (South of Caspian Sea) become a serious challenge for operation and cost efficiency.So far, different solutions have been suggested to solve this problem, including breakwater extension, groin construction, by pass and also increasing the reflectioncoefficient of the western breakwater of the port. However, in order to find the optimal solution, a comprehensive study on sediment transport regime is required.Harbor sedimentation is an important problem to be addressed, especially within the access channel. Noshahr harbor (from 1939) had no sedimentation problem until1988. Then dredging became necessary at the harbor entrance. The dredging rate was about 100 000 to 120 000 m3/year for several years. However, it has been increasedto about 200 000 m3/y in the last three years [1]. Several factors have been studied in order to describe the specific trend of sedimentation along Noshahr Harbor lifetime.Among them are the sea level change, modifications in the harbor layout, and the effect of road construction along Chaloos River near the harbor [2].
