Background: Flood waters still inundated the half-completed hydro-electric dam here at Kariba today, though the Zambesi showed signs of subsiding a little.
After toppling over a temporary road bridge at the dam last week, the river just failed to snatch down a suspension foot-bridge which was rained by about 12 feet two days ago. The Zambesi was today running at the rats of 40 knots beneath the footbridge.
British and French engineers have saved the foot bridge, removed the landslips that had partly blocked the main approach roads to the township and were busy rigging a third "Blonding" cable to supplement the two already working, swinging across the turbulent chase with loads of material and engineers to rescue work on the isolated north bank.
But to stop the charming waters from scouring out the foundations of the coffer dam they could do nothing, only watch and make calculations. One factor in these calculations is the rate of flow which remains at about 450,000 cubic feet a second, or 15,000 tons a second. The greatest flow measured in 1957, the highest food year previously recorded, the only 90,000 cubic foot a second.
A second factor is a twelve inch fall of rain upstream four days ago which should reach the early in March. That by itself will not raise the flow any higher than the peak of about two days ago; but if rains fall again be for the dam these will be cause for concern.
The main wall is not in danger even where submerged in the flooded coffer dam. What can happen is that the circular coffer dam foundations will be so weakened as to make further construction inside ti impossible after the flood falls until and nose repairs have been made.
