The report aims at illustrating and displaying the results of numerical models for studying sedimentation tendencies in the Damietta Port area and the current navigational channel, and to evaluate the proposed port layout according to the following pointers:

  • Numerical modeling of the port area, wave and ocean currents motion and their impact on sediment tendencies.
  • Assessment of the current status of the navigational channel and the existing sedimentation problem.
  • Evaluating several proposals and identifying the best of which from an economic standpoint and serving future expansions
Purpose of the Study
Results of Sedimentation Tendencies Study

  1. The extent of the change in seabed depth was presented throughout the period of the study, which lasted for 7 years, assuming that throughout this period no maintenance (dredging) was carried out in the study area.
  2. The study showed that the area west of the port will witness gradual sedimentation at a rate that may reach a total of 1.5 meters after 7 years, with the expectation that the shoreline will broaden, thus a new land will be acquired in the area west of the port.
  3. The area adjacent to the port to the east is expected to have sedimentation of 70.0 meters after 7 years as the shoreline advances in the area adjacent to the port.
  4. The area at the peak of the western breakwater may have very low sedimentation of 0.20 meters.
  5. The area at the peak of the eastern breakwater. The results showed that slaughter ranging from 10.0 to 40.0 meters may occur after 7 years.
  6. The eastern basin area and the area within the western basin may experience sedimentation at a very low rate of 0.10 meters after 7 years.
  7. The area west of the Western Basin: The results of the numerical model showed the occurrence of sedimentation with a total amount ranging from 0.05 m to 0.80 m, after 7 years, for an area not exceeding 20,000 flat meters and a volume not exceeding 3,000 cubic meters.
  8. The turning circle area: The results showed no erosion or sedimentation within it.
  9. The navigational channel: Total sedimentation ranges between 0.05 to 0.3 meters.
  10. Sedimentation reaches 80% in very limited areas on the western slopes of the navigational channel opposite the peak of the western breakwater, assuming that no maintenance is carried out throughout the period of the study.
  11. Comparing the volume of sediments in the current set-up and in the occasion of the proposed plan, it is noticeable that the volume of sediments in the navigational channel decreased by more than 80%. This is due to the protection sustained by the extension of the western breakwater the navigational channel for a distance of 2,200 linear meters, which was exposed to extremely high rates of sedimentation.
Conclusions
We recommend monitoring sediment tendencies after a period of 5 years after construction and re-evaluating the status of the port.Recommendation
