TECHNICAL NOTE ON THE CURRENT FLOOD SITUATION: HYDROLOGICAL FORECAST ON THE NIGER RIVER IN NIAMEY

In the middle Niger in Niamey, the orange alert threshold has begun while further upstream the situation is still normal in Koulikoro and Diré located in Mali. This situation is explained by the role of the Inner Niger Delta (IND) located in Mali which acts as a buffer for water coming from the upstream basin (Guinea, Ivory Coast and Mali). The IND cushions floods from the upstream basin.

The situation in Niamey at the moment is more linked to the contributions of the 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 during the first decade of August continues.
