The Baihetan section of the Jinsha River is from Hulukou Town (Ningnan County, Sichuan Province) to the confluence (Xixihekou) of the Xixihe River with the Jinsha River, 54 km long. In Baihetan Town a large hydro-station is under construction. Previous works pointed out that the Baihetan section was a diverted river section: in this section, the Jinsha River originally flowed southwards, but about 1 Ma ago, flowed northwards. The authors’ investigation in Mianshawan, Xinhuawucun, the Baihetan building site, Cuijiatuo, and Yuba found that during the last 1 Ma, the average incision depth and rate of the Baihetan Section were larger than other sections of Jinsha River.
