After a tributary, the next stage in a river system is typically the main river or parent river into which the tributary flows. This main river may collect water from multiple tributaries, contributing to its overall size and flow. Eventually, the main river may lead to larger bodies of water, such as lakes, seas, or oceans.
The Nile River is located on the continent of Africa and consists of two main branches (the White Nile and the Blue Nile), these merge and become one river known simply as the Nile River. The White Nile is the source of most of the Nile's water and fertile soil. The Blue Nile is the longer of the two rivers.
