how did the nile floods help farmers grow crops
Ancient Egyptian agriculture The Egyptians took advantage of the natural cyclical flooding pattern of the Nile. Because this flooding happened fairly predictably, the Egyptians were able to develop their agricultural practices around it. The water levels of the river would rise in August and September, leaving the floodplain and delta submerged by 1.5 meters of water at the peak of flooding. This yearly flooding of the river is known as inundation. As the floodwaters receded in October, farmers were left with well watered and fertile soil in which to plant their crops. The soil left behind by the flooding is known as silt and was brought from Ethiopian Highlands by the Nile. Planting took place in October once the flooding was over, and crops were left to grow with minimal care until they ripened between the months of March and May. While the flooding of the Nile was much more predictable and calm than other rivers, such as the Tigris and Euphrates, it was not always perfect. High floodwaters were destructive and could destroy canals that were made for irrigation. Lack of flooding created a potentially greater issue because it left Egyptians suffering from famine.[5]
Nile The source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder, although sources do not agree on which is the longest tributary of the Kagera and hence the most distant source of the Nile itself.[18] It is either the Ruvyironza, which emerges in Bururi Province, Burundi,[19] or the Nyabarongo, which flows from Nyungwe Forest in Rwanda.[20] The two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border.
