Water under the bridge?
22 December, 2010
Ten years have passed since publication of the World Commission on Dams’ final report. Suzanne Pritchard spoke to some of those involved in this revolutionary process in the big dams debate. But is WCD still topical now in 2010, or is it all just water under the bridge?

Facing reality on dam development
22 December, 2010
The World Commission on Dams report overlooked the benefits of and improvements made by dams to society, says ICOLD president Jia Jingsheng. In addition, its guidelines were somewhat idealistic. However ten years on, ICOLD believes that the negative impacts of project development should never be suppressed, overlooked or underestimated. The construction and operation of dams and hydropower projects can no longer be considered as a purely scientific and technical matter. A wide range of other aspects are involved today

Building Jinanqiao Dam
29 November, 2010
Yong-Wen Hong and Cheng-Bin Du present details on the design and construction of the Jinanqiao RCC gravity dam, a 160m high structure located in China’s Yunnan Province, in a region of high seismicity

Dam safety and earthquakes
20 September, 2010
IWP&DC presents a position paper of the International Commission on Large Dams (ICOLD), prepared by the Committee on Seismic Aspects of Dam Design

Grande Dixence – an engineering achievement
10 August, 2010
The Grande Dixence hydro power complex in Switzerland is still considered to be one of the industry’s greatest engineering achievements

Tackling the growing problem of sedimentation
09 August, 2010
Worldwide experts will convene in South Africa in September 2010. At the top of their agenda is the growing problem of river sedimentation. Professor Gerrit Basson explains why tackling this issue is of great importance to the dams industry

Conference call - review of the USSD's annual meeting

The US Society on Dams reports on its successful annual conference, held in the US from 12-16 April 2010

Reminder: Call for Abstracts
28 June, 2010
The Swiss Committee on Dams is inviting professionals and researchers in the field of dam design and construction as well as dam owners to the International Symposium ‘Dams and Reservoirs under Changing Challenges’.

Spotlight on Asia
10 May, 2010
Vietnam plays host to the dam community this year. Ahead of ICOLD’s Annual Meeting, IWP&DC gives an insight into dam and hydro power development across Asia.

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
03 March, 2010
Dam engineers and dam owners may not always have a clear idea about the life-span of their projects. Here, Martin Wieland discusses the many factors which could impact on the useful life of a dam

The relationship between large reservoirs and seismicity
08 February, 2010
Following the 12 May 2008 Wenchuan earthquake in China, Chen Houqun, Xu Zeping and Li Ming discuss the question of whether large reservoirs can trigger strong earthquakes

Finding a replacement
05 February, 2010
The design and construction of a replacement dam on difficult foundations was recently completed at a salmon smolt facility in Scotland. RM Doake from AECOM explains how the design process was shaped by working in such an environmentally sensitive area
