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