Zambezi River runoff
A major impact of the construction of the Kariba and Cahora Bassa dams from 1950–1970 was the reduction in the Zambezi River runoff. Before the dam construction, the Zambezi River was
torrential with high flows during the wet season from November to March and relatively low flows in the dry season from April to October. On average, the river discharged 60 to 80 per cent
of its mean annual flow during wet season. Since the dams were built, the wet season runoffs have been reduced by about 40 per cent, whereas the dry season runoffs have increased by about
60 per cent (SADC and SARDC 2008).
