Fig. 11.12 Variation of annual runoff and annual sediment load measured at the Tangnaihai station in the upper
reaches on the Qinghai-Tibet Plateau, the Tongguan station in the middle reaches on the Loess Plateau, and the Lijin
station on the Yellow River delta (after Liu et al., 2008)
annual runoff. As a comparison, the Tongguan station has a remarkable reduction in sediment load and a
slight reduction in runoff from the 1950s to 2006. The fluctuations of sediment load and runoff are out of
phase. Numerous sediment trap dams on the Loess Plateau, about 3,000 reservoirs, and 9 large dams on
