River Discharge to the Coastal Ocean: A Global Synthesis

Flux and fate of Yangtze River sediment delivered to the East China Sea

[1] In 5 recent years (2000–2004), the Changjiang (Yangtze) River has discharged past Datong (600 km from the river mouth) an average of ∼250 million tons (mt) of sediment per year, a decrease of more than 40% since the 1950s and 1960s, whereas water discharge at Datong has increased slightly. Water and sediment discharge data from the upper, middle, and lower reaches of the river suggest that the reduction of the Changjiang sediment load has occurred in two phases between 1950 and 2002: following the closure of the Danjiangkou Reservoir on the Hanjiang tributary in 1968 and following the installation of numerous dams and water-soil conservation works in the Jialingjijang catchment after 1985. As the Three Gorges Dam (TGD) started operating in 2003, the Changjiang entered a third phase of sediment reduction with annual sediment loads at Datong less than 200 mt/yr. Upon completion of the Three Gorges Dam (TGD) in 2009, the sediment load at Datong will decrease to ∼210 mt/yr for the first 20 years, then will recover to ∼230 mt/yr during 2030–2060, and will reach ∼310 mt/yr during 2060–2110. From the sediment budget and sediment erosion data for the Changjiang subaqueous delta, it can be assumed that the delta will be eroded extensively during the first five decades after TGD operation and then will approach a balance during the next five decades as sediment discharging from TGD again increases.

Clay minerals in 15 surficial samples and 5 profile samples from the Yangtze Delta plain were analyzed by X-ray diffraction. The result shows that clay mineral assemblage of the surfical sediments arc distinguished by the coastline 7 500 - 8 000 a BP, indicating different sediment sources and sedimentary environments. The change of content of illite vs. kaolinite in the profile sediments reflects the climate fluctuations since late Pleistocene.

Distribution of Clay Minerals in the Yangtze Delta Plain and Its Paleoenvironmental Implication(Chinese)

With paleomagnetism and AMS14C dating results, we reconstructed the depositional environmental evolution and marine transgression events during the Late Quaternary by examining the lithology, grain size, magnetic properties, and foraminifera of sediments from a borehole WJ in the Taihu plain of southern Yangtze Delta, China. We also investigated the application of magnetic proxies to distinguishing depositional environments in the estuarine-deltaic area. The results show that the sediment sequence of borehole WJ could be divided into four periods including Mid-Pleistocene stage I, Mid-Pleistocene stage II, Late Pleistocene, and Holocene. Their depositional geomorphological conditions were fluvial-lacustrine plain, coast-terrace, mouth bar-estuary-tidal flat-terrace, and lacustrine plain, respectively. Three transgression events were revealed by the borehole WJ, which happened during the late stage of Mid-Pleistocene, marine isotope stage (MIS) 5 and MIS3 of Late-Pleistocene. The MIS5e transgression was the strongest one and the transgression in the late stage of MIS3 intensified significantly. Magnetic properties were strongest in the tidal flat and mouth bar sediments, with notably high values of χlf, SIRM and HIRM.
