HYDROLOGICAL FORECAST ON THE NIGER RIVER IN NIAMEY
In the middle Niger in Niamey, the orange alert threshold is reached this Sunday August 18th, 2024 while further upstream the situation is normal at the Koulikoro station, orange at the entrance to the DIN at Nantaka station and yellow at the exit of the DIN at Diré hydrometric station in Mali. This situation is explained by the role of the Inner Niger Delta (DIN) located in Mali which acts as a buffer for water coming from the upstream basin (Guinea, Ivory Coast and Mali). The DIN cushions floods from the upstream basin.
The situation in Niamey at the moment is more linked to the contributions of the right bank tributaries (Gorouol, Dargol, Sirba) and the significant local precipitation observed. The months of August and September 2024 will be marked by significant and rapid variations in the water level in the Niger River and its tributaries if the rainfall observed since the beginning of August continues.
