The modern dam engineer
15 February, 2018
Like many industries, the dam industry is influenced by both internal and external factors which can prompt change. IWP&DC was interested in finding out if such elements have affected the engineer’s working life when inspecting dams. We asked members of the industry for their own thoughts about the role of the modern dam engineer: Has this changed in recent years? Are engineers faced with increased challenges? And will this role continue to evolve?

Designs aspects of Deriner dam
08 July, 2008
Upon its completion in 2010, Deriner dam on the Coruh River will be the highest arch dam in Turkey. Dr Martin Wieland, Martin Aemmer and Roland Ruoss discuss how, during the dam design, the safety evaluation earthquake with a peak ground acceleration of 0.35g and the maximum flood of 10,110m3/sec had to be considered

Focused for the future
10 February, 1999
Electrowatt Engineering has found its focus, with Jaakko Poyry, as a purely engineering company. Janet Wood took a look into the future with members of the Energy Division

A model system
10 February, 1999
The Dniester river in Ukraine has been greatly affected by the dams now in place and a planned pumped storage plant would likely cause more damage. Would a buffer reservoir help solve those problems? Some answers were obtained when the system was modelled in a report for the World Bank.

A co-operative approach to refurbishment
11 December, 1998
The need for peak power has prompted Bulgaria to re-assess the condition of its hydro power facilities. Peter Jedelhauser spoke to Suzanne Moxon about Electrowatt Engineering’s role in Bulgaria’s ambitious refurbishment programme

A unique opportunity
11 May, 1998
Large dam projects cause furious debate. The World Commission on Dams was formed in November 1997 to help balance energy needs and environmental concerns in such projects. Richard E Bissell* explains the Commission’s genesis and goals

‘Greening’ Ralco
13 April, 1998
Construction is due to start this year on Chile’s largest hydro power station – the 570MW Ralco plant. Swiss company Electrowatt Engineering has been given the task of drawing-up an environmental management programme for this project which has been the target of ‘green’ activists in recent years. Robert Zwahlen* and Pablo Durán** discuss how such a programme will enable Ralco to form a good working relationship with the surrounding environment
