river in southeastern Zimbabwe rising at Gweru in the Highveld and flowing southeast to Hippo Valley at the confluence with the Shashe River in the Middleveld. It continues across the Lowveld and joins the Sabi River near the Chivirigo (Chivirira) Falls at the Mozambique border, after a course of 260 miles (418 km), to form the Save River. Among the Lundi's great network of tributaries are the Ingezi, Tokwe, Mtilkwe, and Chiredzi rivers. In its upper reaches the river is arrested by Gwenora Dam, and its lower section is incorporated into the Sabi-Limpopo Irrigation Project.
