Kouga dam is a 69 m above riverbed high double curvature concrete arch dam located on the Kougha River in the Eastern Cape Province of South Africa and completed in 1969. The major concern at the dam is the swelling of the concrete due to chemical reaction (SCR) (SCR is also generally known as Alkali-Aggregate Reaction (AAR)). This has the potential of compromising the long-term integrity of the dam especially the arch action during earthquake loads. The importance of proper dam safety surveillance before making any decision on the rehabilitation of dam is highlighted by a discussion of the dam safety surveillance results.
