Abstract: The erosion, transport and redeposition of sediments shape the Earth's surface, and a ect the structure and function of ecosystems and society 1,2 . The Yellow River was once the world's largest carrier of fluvial sediment, but its sediment load has decreased by approximately 90% over the past 60 years 3 . The decline in sediment load is due to changes in water discharge and sediment concentration, which are both influenced by regional climate change and human activities. Here we use an attribution approach to… Show more

“…Given the better correlations of runoff and PF with sediment load, the operation of dams could play an important role in the sediment load change through (extreme) runoff regulation in the upstream part of the Lancang-Mekong River. Figure 6 indicates that, at the 99% confidence level, the annual LF had nonsignificant negative correlation with sediment load over the past 50 years (Figure 6b), and the correlation was weaker than that of PF (Figure 6a Overall, the increasing trend in sediment load agrees with prior search [41][42][43][44][45], and based on the significant increasing trend of runoff and its significant positive correlation with sediment load, it can be inferred that the increase of sediment load could be mainly attributed to the increase of runoff caused by slight increase of precipitation and land cover change (i.e., from arable and Overall, the increasing trend in sediment load agrees with prior search [41][42][43][44][45], and based on the significant increasing trend of runoff and its significant positive correlation with sediment load, it can be inferred that the increase of sediment load could be mainly attributed to the increase of Overall, the increasing trend in sediment load agrees with prior search [41][42][43][44][45], and based on the significant increasing trend of runoff and its significant positive correlation with sediment load, it can be inferred that the increase of sediment load could be mainly attributed to the increase of runoff caused by slight increase of precipitation and land cover change (i.e., from arable and forested land to construction land since the mid-1980s in Yunnan [22]) in the upstream part of the Lancang-Mekong River since 1980.…”

“…Thus the effects of dam construction should not have a predominant effect on the runoff reduction in CM. However, the impact of dam construction was more easily observed through local in situ measurements (Xu et al, 2004;Wang et al, 2015). Dams decrease the runoff coming out of a catchment because water is retained as soil moisture in dam area.…”
