Kerbi
The Kerbi rises among the Dusse-Alin, Yam-Alin and Ezop ranges and flows into the Nimelen, a tributary of the Amgun. Its wooded mountain basin forms part of the extensive river system that reaches the lower Amur. The river descends through a landscape of taiga, streams and wetlands, where seasonal changes in water level affect the valleys. The waterways connect the inland hills with the wider Amgun basin.
