 The Noun |
||
The Noun is a river in Cameroon .
course
The river is one of the main tributaries of the Mbam. It has its sources in the Oku massif on the slopes of Mount Kilum. In its course it receives water from the rivers Mifi North and South and the Monkie. On its way it flows through the city of Bafoussam before flowing into the Mbam at Bafia .
Hydrometry
The flow rate of the river was measured in m³ / s in Bafoussam, 141 km above the mouth.
Drainage management
The Noun is dammed in its upper reaches in the Bamendjing Reservoir . It has a storage volume of 1,850 million m³. Due to the strong seasonal fluctuations in the flow of the Sanaga (factor 10), a combination of reservoirs was created in the system of Cameroon's largest river. The Mbakaou Lake , the Bamendjing and the Mapé Reservoir , as well as other smaller reservoirs, are not used to generate electricity. The national energy producer Eneo (formerly AES Sonel) uses these reservoirs to regulate the amount of water in the Sanaga. At Lom was Kraftwerk Lom Pangar built, the dam can store 6 billion cubic meters of water. This compensates for fluctuations in discharge and optimizes electricity generation at the Edéa and Song Loulou power plants on the lower reaches of the Sanaga.
