The Bani is a river in Mali .

course

It is a right tributary of the Niger with a length of 430 kilometers. It arises 100 kilometers east of Bamako as the confluence of the Baoulé and Bagoé rivers and flows into the Niger near the city of Mopti .

Water management

Every year the river floods an otherwise arid area in which 500,000 people live. It is planned to build the Talo Dam , a five meter high and 295 meter long dam wall near the city of San in the Ségou region , in order to be able to store the river water over the year. In the event of a flood, the wall would be flooded and water should be drained off in a controlled manner in the dry. Among the residents of Djenné living downstream, for example , the plan led to violent protests.

history

Already Herodotus mentions the Bani as "navigable river" to a Persian delegation had traveled in search of the gold country.

Hydrometry

The flow rate of the river was measured over 72 years (1922–94) in Douna , a town in Mali, about 150 kilometers upstream from the confluence with the Niger. The mean annual flow rate observed in Douna during this period was 513 m³ / s.
