Upper Yangtze (Yibin to Fuling)
Yangtze basin, China
Rivers and surface water
- Type
- River or surface water
Main channel of the Yangtze sampled from 14 to 22 July 1996 (high water). Dissolved silicon 97 to 121 µmol/L, suspended matter with 52 to 57 % SiO2; dissolved silicon is heavier than suspended matter by 1.0 to 3.7 ‰. Sichuan Basin reach, before the Min, Tuo, Jialing and Wu confluences. Indicative coordinates (middle of the reach).
