Zambezi the overflow of the Zambezi in the rainy season. The delta of the Zambezi is today about half as broad as it was before the construction of the Kariba and Cahora Bassa dams controlled the seasonal variations in the flow rate of the river. Before the dams were built seasonal flooding of the Zambezi had quite a different impact on the ecosystems of the delta from today as it brought nutritious fresh water down to the Indian Ocean coastal wetlands. The lower Zambezi experienced a small flood surge early in the dry season as rain in the Gwembe catchment and
Munyati River the Mupfure River (also known as the Umfuli). Below this point, the river is often referred to as the Sanyati. After a total of the river flows into Lake Kariba (the section of the Zambezi between the Kariba Dam and the Batoka Gorge), making it part of the Zambezi Basin. The river flow is highly variable, reflecting the sharp distinction in the local climate between dry and wet seasons. Between December and May it flows strongly and is about deep on the plateau, and in breadth (although less deep) on its lower reaches. During the rest of the year, it
