Nigeria’s Hydrological Services Agency has warned residents living near the River Niger and its floodplains to immediately relocate over fears of imminent flooding.
According to the service’s statement, the middle portion of the Niger Basin experienced high flows last week with the flood advancing into the Lower Niger.
NIHSA noted that both Kainji and Jebba dams were already spilling water downstream.
The agency further indicated that flash floods were expected to occur in over 30 Nigerian districts.
Minister of Water Resources, Mr Suleiman Adamu, explained that water levels on River Niger and Benue, among other major rivers, would rise and remain abnormally high during this rainy season.
He raised concern that some dams in the country were also getting silted up, with the storage capacity reducing. He said this would cause a lot of water to be spilled through the waterways.
On July 15, 2018, the Nigeria Meteorological Agency warned that many parts of the country were likely to experience flooding due to a shift in rainfall patterns caused by climate change (GSM).
Prof Sani Mashi, while giving the warning, said that distortions had occurred in the pattern of rainfall leading to a variation in the amount of rain expected in the country.
He explained that in line with the Agency’s 2018 Seasonal Rainfall Prediction, so much water would be made available on the surface, between the last week of July and end of August, that the ground would not be able to absorb it.
GSM = influx of Cosmic Rays = increase in Cloud nucleation = more Flooding
