Here we provide global estimates of the seasonal flux of sediment, on a river-by-river basis, under modern and prehuman conditions. Humans have simultaneously increased the sediment transport by global rivers through soil erosion (by 2.3 ± 0.6 billion metric tons per year), yet reduced the flux of sediment reaching the world's coasts (by 1.4 ± 0.3 billion metric tons per year) because of retention within reservoirs. Over 100 billion metric tons of sediment and 1 to 3 billion metric tons of… 
Quantifying drivers of the sediment load reduction in the Yellow River Basin
Human activities have significantly changed the transport and fluxes of terrestrial sediment of global rivers, trapping over 100 billion metric tons of sediment in reservoirs worldwide, reducing the
The role of dams in the global sediment budget
Dams and their associated reservoirs are a key element of water resource development in most areas of the world and dams have been constructed on many of the world’s large rivers. The presence of
Global trends in water and sediment fluxes of the world’s large rivers
Earth’s sediment cycle during the Anthropocene
The global sediment cycle is a fundamental feature of the Earth system, balancing competing factors such as orogeny, physical–chemical erosion and human action. In this Review, values of the
Reduced sediment transport in the Yellow River due to anthropogenic changes
The erosion, transport and redeposition of sediments shape the Earth's surface, and affect the structure and function of ecosystems and society(1,2). The Yellow River was once the world's largest


Geomorphic/Tectonic Control of Sediment Discharge to the Ocean: The Importance of Small Mountainous Rivers
Analysis of data from 280 rivers discharging to the ocean indicates that sediment loads/yields are a log-linear function of basin area and maximum elevation of the river basin. Other factors
Environmental degradation by mud in tropical estuaries
Abstract. In wet tropical countries, the intense rainfall and the lack of effective restrictions on human activities in the river catchment leads to increased rates of soil erosion. This has
Budgets of soil erosion and deposition for sediments and sedimentary organic carbon across the conterminous United States
The fate of soil organic matter during erosion and sedimentation has been difficult to assess because of the large size and complex turnover characteristics of the soil carbon reservoir. It has been
