Three Gorges primarily famous for its scenery, the Three Gorges region is also historically and culturally important in China. Many settlements and archaeological sites are in danger of being submerged by the rising reservoir of the Three Gorges Dam. Due to the lithological conditions of its different regions, the valleys of the Three Gorges are narrow in some areas and broad in others.

As the limestone bed is gradually undercut, parts of it fall into
Grand Inga Dam Grand Inga Dam The Grand Inga Dam is a proposed hydroelectric dam on the Congo River at Inga Falls in the Democratic Republic of the Congo. The proposed dam is the fourth and largest of the Inga dams, from Inga-I, from Inga-II, and from the proposed Inga-III. The dam has an expected generating capacity of , with 52 turbines each with a capacity of . This is close to twice the capacity of the Three Gorges Dam, which is currently known as the largest energy-generating body ever built. Inga Falls on the Congo River is a group of rapids (or
