大巴山
The southern slope of the Daba Mountains drains into the Sichuan Basin or directly into the Yangtze via short streams that flow into the river in the Three Gorges area, such as the Shen Nong Stream. The northern side drains into the Han River, a major tributary of the Yangtze, which, however, does not join the Yangtze until some hundreds kilometers to the east (in Wuhan).
