why did the nile river become a center for early civilization
River valley civilization Egypt also created irrigation systems from its local river, the Nile River, more intricate than previous systems. The Egyptians would rotate legumes with cereal which would stop salt buildup from the fresh water and enhance the fertility of their fields. The Nile River also allowed easier travel among the civilization, eventually resulting in the creation of two kingdoms in the north and south areas of the river until both were unified into one society by 3000 BC.[7]
Nile The Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile (Amharic: ዓባይ?, ʿĀbay[6][7]) begins at Lake Tana in Ethiopia[8] and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.[9]
