Where does rehabilitation fit into the South African dam safety picture?

A brief outline of the present methodology used in DWA (the dam owner) is presented in the full paper. The reults of these analyses are summarised in a series of graphs depicting the various hazards and finally the risk level. An example of these graphs is presented in figure 1 below. Note that the various impacts as well as the risk level are not points on the graphs but areas indicating the confidence levels of the results.
