How many months per year does the Nile River flood?
When did the Nile flood? The River Nile flooded every year between June and September, in a season the Egyptians called akhet – the inundation. Why did the Nile Flood? Melting snow and heavy summer rain in the Ethiopian Mountains sent a torrent of water causing the banks of the River Nile in Egypt to overflow on the flat dessert land. Why does the Nile not flood now ? The construction of the Aswan Dam in the 1960’s meant that from 1970 the annual flood was controlled.
