Zambezi River
The Zambezi River basin and its drainage network.
The Zambezi River typically reaches its maximum flow during the months of March or April. This seasonal pattern is driven by the region's rainy season, which occurs from November to April, during which the upper Zambezi receives nearly all of its annual rainfall. By contrast, the river's discharge diminishes significantly to less than 10 percent of its maximum during October or November.12
