Abstract: 
Kouga Dam is a 72 m high double curvature arch dam constructed during the 1960’s. The dam has been earmarked for rehabilitation in several phases mainly to address deep-seated foundation movements on the right flank and swelling of the lower part of the arch due chemical reaction. The proposed rehabilitation phase addressing the change in distribution of forces from the dam wall onto its foundation as well as problems experienced with the maintenance and operation of the chute spillway is described. The integrity of the central arch with the possibility to raise the dam progressively in subsequent phases is discussed briefly. The use of Lombardi’s slenderness coefficient graphs to evaluate the feasibility of five scenarios of the chosen options during the preliminary design of the rehabilitation works is demonstrated.
