The mean annual runoff of the Olifants River catchment is 1 220 000 000 m3. (Ref.1) | ||||||||||||||||||||||
|
Winter floods occur wherever heavy rain falls in the catchment. Major flooding in 1925 caused the estuary mouth to assume its current configuration. . There is little river flow in the summer. Period with highest flows is from June to September. Both the Olifants and the Doring Rivers have rapid run-off characteristics.(Ref.1) | ||||||||||||||||||||||
|
The Olifants River mouth is permanently open on the northern side. On the southern side the estuary is mostly isolated from the sea by a sandspit.(Ref.1) | ||||||||||||||||||||||
