Karebbe hydro-combine and failsafe spillway
20 August, 2012
PT Vale Indonesia Tbk operates a mining and nickel-smelting operation on the Indonesian island of Sulawesi. The nickel-processing plant is largely powered by hydroelectric generating stations on the Larona River. When the company decided to increase nickel production in 2003, SNC-Lavalin was invited to enter a design competition for a new hydroelectric facility to increase their generation capacity. The successful design benefitted from two interesting features highlighted in this paper: a distinctive hydro-combine powerhouse arrangement; and a unique failsafe spillway arrangement.

Engineering ingenuity
20 August, 2012
Once described as a drowning machine, Calgary Bow River weir could not be removed due to the strategic importance it plays in supplying irrigation water. Now, however, it is heralded as an engineering success.

Improving Pointe du Bois
20 August, 2012
Early works are underway for spillway replacement at Pointe du Bois dam, in Manitoba, reports Patrick Reynolds

Award winning scheme from NYPA
20 August, 2012
The New York Power Authority (NYPA) has received an Outstanding Stewards of America’s Waters (OSAW) Award from the National Hydropower Association (NHA) for the habitat restoration of Little Beaver Island, the fourth such award for the power utility

Unlocking hydro potential
20 August, 2012
Hydropower still has enormous unfulfilled potential in the US. Recent reports suggest that the country’s conventional hydro fleet could be expanded by 15% - without the construction of a single new dam. But can hydro find the right key to unlock such growth potential? Although the Department of Energy has been applauded for its research efforts into energising non-powered dams, the US Army Corps of Engineers has also been criticised for excluding hydro from recent proposals. Suzanne Pritchard reports.

Las Vegas in luck
20 August, 2012
A Falcon ROV is playing a key role in a project to keep fresh water flowing to the US city of Las Vegas

At the hub of it all
29 June, 2012
A new seawater pumped storage plant is set to play a central role in an ambitious energy export scheme known as MAREX. Irish company Organic Power gives more details about the development taking place on Glinsk Mountain in County Mayo.

Plan for Coire Glas pumped storage project, UK
29 June, 2012
Planning approval is being sought for the Coire Glas project in Scotland – the first pumped storage scheme in the UK for decades, reports Patrick Reynolds

Real-time monitoring of sediments
29 June, 2012
The real-time monitoring of sediments is now a reality following the development of a new system which measures the total sediment concentration and size distribution of suspended sediments in rivers, writes O.A. Mikkelsen, Y.C. Agrawal and H.C. Pottsmith

Making a case for sedimentation
29 June, 2012
According to the International Sediment Initiative (ISI), sedimentation issues are often ignored because the scale of the problem can seem too overwhelming. Recent research by ISI is working towards creating a holistic approach to the remediation and conservation of surface waters, with the management of dams and reservoirs playing a key part. Suzanne Pritchard takes a closer look at ISI’s recent interim case study report.

Pushing projects in Latin America
29 June, 2012
Cheves and Olmos, in Peru, and the Chiriqui Viejo cascade, in Panama, are among the many projects making good development progress in Latin America, reports Patrick Reynolds

Pilot projects ready for take-off
28 June, 2012
Hydrokinetic river developments continue to progress in the US. Verdant Power steps up the pace with the first pilot project licence for its East river scheme.

Queensland floods: the final report
28 June, 2012
Years of drought had prompted complacent attitudes towards flood protection and dam management. This statement, from the head of the Queensland flood inquiry, prefaces the final report into catastrophic flood events which engulfed an Australian state more accustomed to water shortages. With the launch of the inquiry’s findings being caught up in a web of political and ethical intrigue, those with a genuine interest in flood risk management were urged to read all of the report very closely. After its complex investigation, the Queensland Floods Commission of Inquiry hopes that lessons learnt from these events will not be forgotten. Suzanne Pritchard reports.

3D monitoring of turbine-generator sets
28 June, 2012
A 3D visualization model can be used to carry out a successful simulation of equipment maintenance, as a project at the Gezhouba Hydropower Station has shown.

Hume-ward bound - detailing the Sea to Hume Fishway programme
26 June, 2012
Restoring migratory passage for native fish along Australia’s River Murray has been an extensive undertaking. It has spanned more than a decade in the shape of the Sea to Hume Fishway Programme. When completed, fishways costing A$55M will have been constructed at weirs and barrages, which was considered to be an acceptable cost to provide best practice fish passage.

Storage and pumped-storage plants in Switzerland
26 June, 2012
The facilitation of renewable energy technologies should also consider energy storage. Nicolas Crettanand looks at the potential for small storage and pumped-storage plants in Switzerland

Innovative modelling for Californian high hydro
26 June, 2012
California’s high elevation hydropower system with more than 150 power plants provides 74% of the US state’s hydropower. Given that studying such a large system with conventional hydropower modelling methods would be tedious and costly, Kaveh Madani and Jay Lund have developed a new model (EBHOM) that can be used for large-scale hydropower planning studies in California with reasonable computational effort and time.

Shouting out for innovation
26 June, 2012
Polish company CEDI is working hard to enhance its presence in the small hydro industry at home and further afield. In doing so it has established a close working relationship with local Cracow University of Technology and clearly voices its belief that technological innovation is the way forward for small hydro.

Climate change versus Swiss hydro – what happens next?
26 June, 2012
A recent research collaboration has updated previous estimates about climate change’s influence on future Swiss hydro power production. Rolf Weingartner, Bruno Schädler and Pascal Hänggi from the University of Bern give an interesting insight into their work.

Pushing the green concrete envelope
26 June, 2012
Scientists believe they have made a revolutionary breakthrough in the development of a new cement which not only has green credentials but, Blue World Crete believes, will give Portland cement a run for its money.
