The White Nile is one of the two main tributaries of the Nile River, which is the longest river in the world. It originates from Lake Victoria in East Africa and flows northward through countries like Uganda and South Sudan. The river is known for its clear waters and is an essential water source for the regions it traverses. The White Nile meets the Blue Nile at Khartoum, the capital of Sudan, where they combine to form the main Nile River. This confluence is significant for agriculture and transportation in the region. The river supports diverse ecosystems and is vital for the livelihoods of millions of people living along its banks.
