How have the river discharges and sediment loads changed in the Changjiang River basin downstream of the Three Gorges Dam?

Streamflow and sediment loads undergo remarkable changes in worldwide rivers in response to climatic changes and human interferences. Understanding their variability and the causes is of vital importance regarding river management. With respect to the Changjiang River (CJR), one of the largest river systems on earth, we provide a...

Mechanisms of hyperconcentrated ßood propagation in a dynamic channel-floodplain system

The downstream peak discharge increase during hyperconcentrated floods in the Yellow River has been attributed to bed erosion, roughness reduction and floodplain effects. While great improvements have been made on the nderstandings of the roles of bed erosion and roughness reduction, the effects of floodplain remain poorly understood. Here, as a...

Progradation and erosion of a fine-grained tidally dominated delta: A case study of the Jiangsu coast, China

A large proportion of the world population lives in the coastal zone, which is facing a variety of natural and anthropogenic impacts on its evolution. A better understanding of coastal evolution can be obtained when it is based on an accurate knowledge of coastal dynamics. This thesis aims to study the long-term (hundreds of years) coastal...
