The Abuna River (called Spanish: Río Abuná in Spanish and Portuguese: Rio Abunã in Portuguese) is a river in South America. It is a very important river because it forms part of the natural border between two countries: Bolivia and Brazil.
This river is part of the huge Amazon Basin. The Amazon Basin is like a giant bowl where many rivers flow into the mighty Amazon River. The Abuna River helps define the northern border of Bolivia and the northwestern border of Brazil.
The Abuna River: A Border River
The Abuna River stretches for about 375 kilometers (233 miles). That's a long way! It starts from small streams in the eastern part of the Andes mountains in Peru. The Andes are a very long mountain range in South America.
Journey of the Abuna River
As the Abuna River flows, it becomes wider and deeper. For about 320 kilometers (200 miles) of its lower part, boats can travel on it. This means it is "navigable" for a good distance. This makes it useful for transport and travel in the region.
Joining a Bigger River
The Abuna River eventually meets a much larger river called the Madeira River. The Madeira River is one of the biggest rivers that flows into the Amazon River. When two rivers meet, it's called a "confluence."
The Abuna River joins the Madeira River near a place called Manoa in Bolivia. Right across from where the rivers meet, there is a town named Abunã on the Brazilian side. This town shares its name with the river.
