kariba dam plunge pool rehabilitation

The world-class project at Kariba Dam will see the building of a temporary cofferdam downstream of the main wall, allowing the deep plunge pool to be drained, reshaped and stabilized. This will reduce the backward scour in the pool, created by water released by sluices in the dam wall; the concern is that this scouring is edging towards the dam foundations.
