Sediment reduction in Yangtze River threatens estuary erosion-deposition balance.
The researchers looked at how sediment from the Yangtze River affects erosion and deposition in the Yangtze Estuary. They used data from river stations and field measurements in the estuary. They found that sediment load in the river has decreased, leading to less sediment deposition in the estuary. This decrease is mainly due to a reduction in coarse grains in the estuary.
