A few projects - major and minor - have indeed been initiated to extract residual gold at some of the older Witwatersrand dumps, but little effort has been spent over the years in attempts to exploit the vast available quantities of deposited fine tailings for some other beneficial use. In any event, the gold law places restrictions on the exploitation of dump material for any purpose other than further gold extraction.

The annual JD roberts Award is sponsored by Murray & Roberts and held in partnership with the CSIR. Instituted by Murray & Roberts in the late 1970s in remembrance of one of the group's founding fathers, Dr JD (Douglas) Roberts, the award recognises and promotes competitive and environmentally sustainable solutions to human dilemmas and encourages scientific research into technology that will enhance the quality of life of all South Africans.
Academies of Engineering worldwide are playing an increasingly supportive and consultative role, working in concert with governments, business, academia and other engineering institutions in times where the competitiveness of nations is technology driven. In most developed and developing nations, Academies of Engineering (which include all disciplines of engineering) are deemed to be so important that they report directly to the office of the Head of State.
The SAICE Project Management Division has amongst its other goals and objectives taken over the duties of the Construction Division. One of these duties was the presentation of the Basil Read Award, usually performed in conjunction with the Sandy Jamieson Memorial Lecture. However, the demise of the Construction Division some years ago resulted in the failure to arrange the Memorial Lecture and to make the Award. The Project Management Division is considering whether this omission should be corrected.
The South African Association of Consulting Engineers (SAACE), at their prestigious 2008 Engineering Excellence Awards function, held on 6 August at the Sandton Sun, not only rewarded engineering excellence, but also launched its new identity, Consulting Engineers South Africa (CESA).
A simple example of the Markov process for a reservoir is outlined and a chart for the estimation of the yield of a reservoir with a gamma inflow distribution is presented in terms of storage ratio, coefficient of variation of annual inflow, reservoir evaporation characteristics and probability risk level.
