Abstract: (40 Views)
Shahid Beheshti Port stands as a critical maritime infrastructure in Iran, serving as a pivotal transit hub for goods destined for Central Asia. This research aims to elucidate the sedimentation dynamics within Chabahar Bay, both before and following the expansion of the Shahid Beheshti Port. The study employed various modules of the MIKE21 hydrodynamic modeling suite to achieve this objective. The modeling results, comparing pre- and post-development scenarios of Shahid Beheshti Port, reveal that sediments circumnavigate the breakwater before entering the area between the Beheshti breakwater and Kalantari Port. The region north of Kalantari Port, characterized by the rocky Lipar coast and seabed, predominantly experiences erosion, with occasional sedimentation events. The coastal stretch extending from Tis Port to the beach area exhibits a complex interplay of depositional and erosional processes. Erosion rates in this sector are substantial, ranging from approximately 14,000 to 19,600 cubic meters annually. A desalination plant situated along the western coastline acts as a significant sediment trap, with pronounced accumulation on its eastern flank. Conversely, the western side of this structure is subject to erosion due to local current patterns.

Highlights
A calibrated MIKE21 model successfully simulated wave, current, and sediment dynamics in Chabahar Bay.
Port development reduced wave energy, modified hydrodynamic circulation, and altered sediment transport pathways, increasing deposition between Shahid Beheshti and Shahid Kalantari Ports while identifying erosion-prone coastal zones.
The results provide a reliable tool for sustainable port development and coastal management.
