The Baihetan section of the mas-microsoft-com:office:smarttags" />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.
