Enhancing the image of water development schemes
07 May, 2010
Public awareness and acceptance will play significant roles in future water development projects. Peter Mulvihill believes that we should be working towards a long term commitment to enhance the lifelong image of water development schemes. It should not just be a quick fix obtained for project approval

CFRDs in highly seismic regions
14 April, 2010
Until the Wenchuan earthquake of 12 May 2008 no large concrete face rockfill dam (CFRD) was subjected to strong ground shaking. Quite a few dam engineers were of the opinion that CFRDs are inherently safe against earthquakes, because any leakage in the concrete face would not lead to the failure of the dam. Even if such a state could be achieved excessive leakage could not be tolerated and the reservoir would have to be drawn down if severe damage of the concrete face and/or the water proofing system has to be assumed. In this paper the main measures to be considered to achieve a safe CFRD in highly seismic regions are discussed

Life-span of storage dams
