Port of Gennevilliers Port of Gennevilliers The Port of Gennevilliers is the largest port in the Ile-de-France and the largest French river port. It is located in the commune of Gennevilliers in the north of the Hauts-de-Seine. The port is primarily a commercial port. It is an important delivery terminal for semi-finished non-perishable freight from lower-Seine (via Le Havre), and also for heavy materials carried by the French canal system. These items are mostly heavy, low value-added bulk materials: sand and gravel, cement, finished building materials (such as metal frames), packaging materials (paper, pallets) or certain dangerous chemicals. The port is suitable for
Seine River (Manitoba) Floodway into what is known as the "Seine River Siphon", which allows a flow of up to ; any additional flow is diverted onto the Floodway. During a wet spring, the river often overflows its banks, sometimes flooding nearby houses. During a dry summer, the river is often reduced to a trickle. Within the city, the Seine travels a tortuously meandering course, reaching the Red River at St. Boniface just north of The Forks. The lower section of its course in the city marks the east-west boundary between the southern section of St. Boniface and the suburb of St. Vital.
