wunder beta🌊Three Gorges: A River Remade
Follow the Three Gorges Project from river engineering to the people, habitats, sediment, and operating choices reshaped by its reservoir.
What you’ll learn
- A river with a country inside itPlace the Yangtze and the Three Gorges in their geographic and human context.The river's scale and the project's competing purposes explain why this valley became a national decision.
- Building a wall across the YangtzeUnderstand how the dam converts height and stored water into flood control, electricity, and navigation.Concrete, turbines, locks, and operating rules turn one barrier into a working river system.
- The water risesTrace how reservoir filling changes landscapes, heritage, livelihoods, and social networks.The million-person relocation was also a remaking of towns, economies, memories, and connections.
- What the dam changesEvaluate the project's continuing effects on sediment, habitats, risk, and future choices.The dam's consequences continue downstream and around the reservoir, making management an ongoing question.
Questions this course answers
Why was the Three Gorges site attractive for hydropower?
The gorge's topography and Yangtze flow made a large head of water available.
What does a gravity dam mainly use to resist water pressure?
The dam's large concrete mass transfers and resists the reservoir's horizontal load.
How does a navigation lock raise a ship?
Gates isolate a chamber while water is added or released to change the vessel's elevation.
Why can resettlement affect more than a home's address?
Livelihoods and social networks are tied to places, not only buildings.
What can a dam do to downstream sediment delivery?
Lower flow speeds inside a reservoir let part of the river's solid load settle.
Why should the project be evaluated over time?
The dam keeps redistributing water, sediment, energy, risk, and access across the basin.
