The Bahr Aouk ( also called Aoukalé in the upper reaches ) is a river in Central Africa . It is one of the largest tributaries in the upper reaches of the Shari , which is the main tributary of Lake Chad . The word Bahr means sea or masses of water in Arabic .
geography
The Bahr Aouk rises in the triangle between Sudan , the Central African Republic and Chad . Its catchment area extends from Darfur , the headwaters of the Tiwal, to the Bongo massif , the headwaters of the Yata. For most of its course it forms the border between the Central African Republic and Chad. In its upper reaches it is called Aoukalé and is connected to the Mare de Tizi via a swamp area. Only after the confluence with the Bahr Kameur is it called Aouk on all maps. From the source it flows in a south-westerly direction towards the city of Sarh (Chad). About 7 kilometers after leaving the Central African Republic, it flows into the Shari, 15 kilometers above the city of Moussafoyo (Chad).
Due to its gentle slope, the Aouk forms a strongly meandering meadow landscape with numerous small lakes in its lower reaches. Seasonal widespread flooding can occur in this area, which is a major source of local fishing. Up to 3,000 tons of fish are caught annually in the marshland created in this way (status: 1992). In the Chad region, these wetlands are part of the Ramsar area des Plaines d'inondation des Bahr Aouk et Salamat , which is of particular importance for migratory birds in the northern hemisphere .
Its main tributary is the Bahr Kamuer. He is also served by Tete and Gourdai from the Central African Republic.
Hydrometry
The flow rate of the river was recorded for 22 years (1952–1974) in Golongosso , a small settlement just above the confluence with the Chari. The mean annual flow rate observed there was 74 m³ / s, fed by an area of 96,000 km², i.e. almost the entire catchment area of the river.
