Seine Commercial craft (barges and push-tows) can use the river from Marcilly-sur-Seine, to its mouth. At Paris, there are 37 bridges. The river is only above sea level from its mouth, making it slow flowing and thus easily navigable. The Seine Maritime, from the English Channel at Le Havre to Rouen, is the only portion of the Seine used by ocean-going craft. The tidal section of the Seine Maritime is followed by a canalized section ("Basse Seine") with four large multiple locks until the mouth of the Oise at Conflans-Sainte-Honorine (170 km). Smaller locks at Bougival and at Suresnes lift the
Muhuri River water into the river from the Bay of Bengal. The Muhuri empties into the Feni at the reservoir formed by the building of the closure dam from where water is taken out through irrigation canals. The project has helped develop inland fisheries, curbed incursion of saline water upriver and kept upstream areas safe from storm surges following cyclones. Muhuri River Muhuri is a transnational river between India and Bangladesh. Rising in Tripura, it flows into Bangladesh where it merges with the Feni near the latter's mouth to the Bay of Bengal. The Muhuri is also known as the Little Feni.
