TLDR
In this article, the authors used hydrographic observations, suspended-sediment measurements, and historical data to identify transport paths and sinks for sediment within the Changjiang estuary and adjacent shelf and estimated that 40% of sediment load in the river is deposited in the estuary, mostly in and seaward of the South Channel.About:

Microplastics in freshwater and terrestrial environments: Evaluating the current understanding to identify the knowledge gaps and future research priorities.
TL;DR: This review critically evaluates the current literature on the presence, behaviour and fate of microplastics in freshwater and terrestrial environments and, where appropriate, draws on relevant studies from other fields including nanotechnology, agriculture and waste management.

Flux and fate of Yangtze River sediment delivered to the East China Sea
TL;DR: In this paper, high-resolution seismic profiling and coring in the southern East China Sea during 2003 and 2004 cruises has revealed an elongated (similar to 800 km) distal subaqueous mud wedge extending from the Yangtze River mouth southward off the Zhejiang and Fujian coasts into the Taiwan Strait.

50,000 dams later: Erosion of the Yangtze River and its delta
TL;DR: Using 50 years of hydrologic and bathymetric data, Wang et al. as discussed by the authors show that construction of approximately 50,000 dams throughout the Yangtze River watershed, particularly the 2003 closing of the Three Gorges Dam (TGD), has resulted in downstream channel erosion and coarsening of bottom sediment, and erosion of the subaqueous delta, and the delta front has devolved from ~125mm3 (1 Mm3 = 1000 000 m3)/yr of sediment accumulation in the 1960s and 1970s, when river sediment load

TL;DR: Foams and fibers were the most abundant type in São João da Madeira, while fibers and fragments were themost abundant in Aguincheira and Estarreja in water and sediment samples, respectively.

Dam impacts on the Changjiang (Yangtze) River sediment discharge to the sea: The past 55 years and after the Three Gorges Dam
TL;DR: In this article, the authors show that the sediment budget and sediment erosion data for the Changjiang subaqueous delta will be eroded extensively during the first five decades after the Three Gorges Dam (TGD) operation and then will approach a balance during the next five decades as sediment discharging from TGD again increases.

Rates of sediment accumulation and particle reworking based on radiochemical measurements from continental shelf deposits in the East China Sea
TL;DR: Radiochemical measurements of 234Th (t1/2 = 24 days), 137Cs (bomb-produced), and 210Pb (t 1 2 = 22y) have been used to characterize rates of mixing, deposition, and accumulation on 100-day and 100-y time scales in East China Sea sediments as mentioned in this paper.

Concepts of sediment deposition and accumulation applied to the continental shelf near the mouth of the Yangtze River
TL;DR: In this article, Radionuclide profiles of 234 Th and 210 Pb within the seabed can be used to determine 100-day deposition rates and 100-yr accumulation rates, respectively.

Development of the Changjiang estuary and its submerged delta
TL;DR: The Changjiang estuary has undergone a progressive progradation seaward of shoals and tidal flats fringing the south bank, merging of linear sandbanks with the north bank, successive filling and narrowing of the estuarine embayment, and a resultant seaward migration of the river mouth as discussed by the authors.

Hydrological characteristics of the Changjiang and its relation to sediment transport to the sea
Shi Yun-Liang,Yang Wu,Ren Mei-e +2 more
TL;DR: In this article, the authors combine the different hydrological regimes in the middle and lower Changjiang to show the influence of southern tributaries (high discharge but low silt content) and the effect of highly silt-laden waters from the upper Changjiang.

Transfer of Water and Sediment from the Yangtze River to the East China Sea, June 1980
TL;DR: The Yangtze River, the fourth largest in the world in terms of sediment discharge, contributes about 500'×'106't annually to the East China Sea as discussed by the authors, a disproportionate part of the load is carried after pea...
