What you’ll learn

  1. A river, three gorges, one decisionPlace the Yangtze and Three Gorges in geographic context and explain why the project had several competing purposes.A natural gorge corridor became the site of a national-scale water, power, navigation, and flood-management decision.
  2. When the river became a reservoirTrace how impoundment changed shorelines, settlements, livelihoods, and social networks.Moving roughly 1.3 to 1.4 million people meant rebuilding ways of life, not just replacing addresses.
  3. What the wall changes downstreamExplain how the dam alters sediment, fish habitat, flood operations, and geological risk.The project's effects continue through water, sediment, slopes, habitats, and operating rules.
  4. How to judge a transformed riverEvaluate benefits and costs across different places and times, using monitoring and distribution as guides.A transformed river must be judged by evidence, long-term consequences, and who receives or carries each outcome.

Questions this course answers

Which statement best distinguishes the Three Gorges from the Three Gorges Project?

Qutang, Wu, and Xiling are natural gorge reaches; the project changed water levels and infrastructure around them.

Why can project goals compete?

Reservoir operations must allocate limited storage and releases among several purposes.

Why is a relocation count incomplete by itself?

People moved with farms, work, social ties, memories, and access patterns that a headcount cannot describe.

What makes resettlement a long-term livelihood test?

A durable outcome depends on rebuilding the means to earn and participate in community life.

What material can a deep reservoir trap?

Slower reservoir water allows some of the river's transported sediment to settle.

Why does flood protection depend on operations?

A reservoir helps only when managers have space and release water in a controlled way.
