Influence of Three Gorges Reservoir on the Upper and Lower Reaches of the Yangtze River in High School Geography

1. Hydrology: reduce downstream flow and reduce running water erosion.

The sediment concentration in the downstream decreases and the velocity slows down.

Sediments in the riparian delta will be significantly reduced.

2. Climate: It will play a certain role in regulating the climate in the upstream inland areas.

3. Geomorphology: Change some landscapes in the upper, middle and lower reaches of the Yangtze River.

4. Impact: The upstream shipping capacity is improved, the upstream water level rises, and the waterway becomes deeper.

Flood disasters in the lower reaches have decreased, and landslides and earthquakes in the reservoir area have increased.

Make some precious wild animals extinct.

Enhance the storage capacity of the Yangtze River.
