Outside the port: The area between the Khireddine and Mustapha jetties exhibits uniform and
parallel isobaths aligned with the coastline. Depths range from -15m to -30m, with an access
channel situated at a depth of -30m. These features indicate a consistent seabed and a gradual
slope.
Inside the port: it can be divided into three parts:
• Old Port Basin: Accessed through the North Pass and located between the Khireddine
and Old Port jetties. The bathymetry in this zone varies from -8m near the quays with
closely spaced isobaths to -20m at the center of the basin, where the isobaths are more
regularly spaced. The basin has a depth of -10m to accommodate large ships. The
decrease in depth near the quays can be attributed to sedimentation.
• Agha Basin: Accessed through the South Pass and protected by the Agha jetty. Depths in
this area range from -6m near the quays with closely spaced isobaths to -12m at the
center of the basin, where the isobaths are more evenly spaced. The depth reduction near
the quays is also caused by sedimentation.
• Mustapha Basin: Accessed through the South Pass and protected by the Mustapha jetty
and Mustapha East Breakwater jetty. Depths in this basin range from -4m near the quays
with closely spaced isobaths to -15m at the center, where the isobaths are more regularly
spaced. There is a -15m access channel to accommodate medium-sized vessels. The
decrease in depth near the quays is a result of sedimentation in this basin.

Bathymetry of the Algiers Marina:
Bathymetry Inside the Marina:
The bathymetric data within the marina area reveals moderately regular and parallel isobaths to
the coastline, indicating a smooth slope and a consistent seabed. Depths range from 0.5 to 2
meters, with the overall basin depths varying from -0.8 to -5.2 meters. The shallowest depths (0.8 to -2 meters) are found near the rooting area, potentially due to the original geomorphology
