Why do Guizhou’s rivers have strong hydroelectric-power potential?

Guizhou’s rivers possess significant hydroelectric power potential primarily due to the province's rugged topography and hydrological characteristics.

The region is part of an old, eroded plateau known as the Yunnan-Guizhou Plateau, which features abrupt relief, steep gorges, and incised valleys. Because the terrain slopes at a steep angle from the center toward the north, east, and south, the rivers experience an abrupt change of gradient. These physical conditions, combined with a high volume of rainfall—which averages 35 to 60 inches annually—create powerful water flow.123

While these factors, along with the presence of many rapids and reefs, make the rivers largely unsuitable for navigation, they provide the ideal conditions for developing hydroelectric facilities.42
