ESHA organizing course on sustainable hydropower

The European Small Hydropower Association (ESHA) is organizing a ten-week postgraduate course on sustainable hydropower.

The course is being held March 1 through May 15, 2010, in Vienna, Austria. All lectures will be held in English. The goal of the course is to provide students with understanding of the technology and design of hydropower, as well as advanced design and sustainable hydropower concepts.

The course is tailored to professionals in the hydropower business, potential investors, students who want to specialize in hydropower, and people interested in this renewable energy sector, ESHA says. Training will cover hydrological data, hydraulic structures, electromechanical equipment, mitigating environmental effects, estimating and optimizing capacity and output, economic analysis, planning principles and engineering processes, status of the current market, and ocean energy.

Upon completing the 30-credit course, participants will receive a postgraduate certificate in Sustainable Hydropower from ESHA.

Hydropower conference in Austria seeks abstracts

Organizers of the 16th International Conference on Hydropower Plants seek abstracts by January 31, 2010, of proposed papers for the conference, “Reliable Hydropower for Safe and Sustainable Power Production.” The conference is being held November 24-26, 2010, in Vienna, Austria.

Submit abstracts of no longer than two pages in English via the conference website: Abstracts will be reviewed by the conference’s reviewing committee. If accepted, authors will be invited to submit a paper by June 30, 2010.

Topics to be discussed at the conference include new projects, refurbishment of existing projects, design and numerical calculation of hydraulic components, pumped storage, maintenance and safety, and small hydro.

The conference is being organized and hosted by the Vienna University of Technology’s Institute for Energy Systems and Thermodynamics.

ICOLD Forum: Concrete specification, quality control

To aid dam designers, engineers, and constructors, the International Commission on Large Dams (ICOLD) offers a technical bulletin on specifying and ensuring the quality of concrete for dams. Bulletin 136, The Specification and Quality Control of Concrete for Dams, was prepared by the ICOLD Committee on Concrete Dams. This committee is made up of 20 members from 19 countries. John Berthelsen, independent consulting engineer in the United Kingdom, was the lead author of the bulletin.

The purpose of this bulletin is to make available a summary of current practice in the specification and quality control of concrete for dams. This bulletin supersedes Bulletin 47, Quality Control of Concrete, published in 1983.

The 122-page bulletin addresses all aspects of the relationship between the specification of concrete, construction procedures, the properties of the hardened concrete, and how quality control is used. The development of concrete for dams from the conceptual stage to finished product is described. It presents a holistic approach, recognizing the interrelatedness of the design and construction process and the roles of both designers and contractors in the production of functional, durable, and economic concrete.
