ABSTRACT

It then became necessary to restore the structural integrity of the upper parts of the arch, secondly, to improve the force distribution on the flanks of the dam, thirdly, to address the operation and maintenance problems experienced with the chute spillways and fourthly, allowing the possibility for the dam to be raised to its full height. Finally, the rehabilitation has to be done in such a way that it does not jeopardise the aesthetics of the dam.
