Dibamba River

The Dibamba River is in the Littoral Region of southern Cameroon, emptying into the Cameroon estuary near the city of Doula.

Location

The Dibamba river has a length of 150 kilometres (93 mi) and a catchment area of 2,400 square kilometres (930 sq mi). Average discharge at the river mouth is 480 cubic meters per second.[1] At its mouth, the river is tidal, and flows into the estuary through mangrove forests that extend south from Doualla to Point Souelaba.[2] Near Douala, the river is crossed by a 370 metres (1,210 ft) T-section girder road bridge built of precast, prestressed concrete in 1983–1984.[3]

History

The Duala people, who today inhabit the region in and around the city of Douala, moved to their present-day location from Piti on the Dibamba river, displacing Bassa-Bakoko cultivators. Duala traditions say they are descendants of Mbedi, son of Mbongo, who lived in Piti.[4] Monneba was a Duala leader on the Cameroon coast in the 1630s, engaged in trading in ivory and slaves with the Europeans. Dutch maps from the 1650s place Monneba's name on the Dibamba River, which is called Monneba's Creek or Channel (Monnebasa Gat).[5]

The Dibamba was the scene of naval hostilities during World War I, when Commander Ralph Stuart Sneyd engaged and sank a large German launch on 10 September 1914, and drove the enemy out of their post at Piti.[6]

Environmental issues
Sand quarry on the Dibamba River

Douala's Bassa industrial zone ends in the estuarine creek formation of the Dibamba River, discharging pollutants. The wetlands are quickly being colonized by invasive species, and a great number of phytoplankton have been identified, some of which are caused by the pollution. Further inland, there are still some patches of permanent swamp forest on the river, but many others have been cleared and drained for oil palm plantation. The fauna of river are not well protected. The African Manatee (Trichechus senegalensis) is endangered.[7]
