Three Gorges of Yangtze River
Three Gorges came into being because of the terrain rising and the strong downward water erosion of this area. Along the banks, fantastic steep peaks and cliffs face each other, generally standing 700 - 800 meters (2,300 – 2,600 feet) high above the water. The narrowest part is less than 100 meters (330 ft).

Downstream of the Three Gorges, typical sections of the Yangtze Gravel are exposed along the trunk Yangtze River at Wuhan, Jiujiang, Anqing, Tongling and Nanjing (Yang et al., 1995; Fig. 1 B).The Yangtze Gravel consists predominantly of medium to coarse sand and rounded to sub-rounded, well-sorted, pebbles and imbricated cobbles …
Unsaturated slope stability around the Three Gorges …
In this paper, model tests on the slope stability of the Three Gorges Reservoir (TGR) area were conducted with S1 sand under three different rainfall and FRWL combinations. Additionally, numerical simulations on the model tests, in which an unsaturated soil constitutive model was selected to describe the mechanical–hydraulic behaviour of ...
Experimental investigation of the interaction between water …
Most landslides induced by reservoir impoundment and rainfall in the Three Gorges Reservoir area of China are usually characterized by bedding-plane shear zones. This paper presents an experimental study of the interaction between water and shear-zone materials. A series of tests, including wetting-drying cycles and soaking tests, were carried out. The …
Three Gorges Project on the Yangtze River in China
China Yangtze Three Gorges Project (TGP), as one of the biggest hydropower-complex projects in the world, serves as the key project for improvement and development of Yangtze River. …
The impact of the Three Gorges Dam on the downstream …
Three Gorges Dam has impacted the pattern of grain-size in the Yangtze significantly. There exists an abrupt sand–mud transition in the channel of the Yangtze Estuary. The Yangtze mud shows an exponential fining along the sediment dispersal in the sea. The mud margin off the Yangtze mouth has retreated due to erosion in recent years.
