Informations

The VenueThe conference venue will be near the city of Vienna at the Conference Center of Laxenburg (Schlossplatz 1, A-2361 Laxenburg). The scientific program will consist of invited lectures, plenary lectures and a workshop about numerical simulation in Hydraulic Engineering. A social program will be organized. Special arrangments for accompanying persons are possible.

ObjectivesToday we have an intensive discussion about the climatic change all over the world. In the near future many efforts will be undertaken to reduce the CO

2 output in any

field of our life. Hydropower contributes today a big part to reach these goals for the future. The production of clean energy supplied by Hyropower Plants is substantially and important. Nevertheless it is necessary to develop the existing potential either by building new Hydropower plants or to refurbish the old existing ones. Both scenarios will have opportunities to reach the goals of reducing the CO

2 output for the future.

Main topicsnNew projects and refurbishment (Pump storage, planning, design, …)nDesign and numerical calculation of hydraulic componentsnProduction methods and materialsnPower production and plant management, climatic scenariosnSmall HydronSustainability and social impacts of Hydropower plants, administration practices

Evening Dinner at the Heurigen.The program for the second evening will be a dinner in a traditional wine- restaurant called “Heuriger“.The best way to reach the “Heurigen”-restaurant is by public transport. There is a bus line 35A into the direction of “Salmannsdorf/Neustift” and has its stop, called “Neustift am Walde”, in front of the restaurant. For those who are not so familiar with the transport system in Vienna we will organize a meeting point and will lead you there.

Further informationyou can find at the homepage of the “Heurigen” Ë www.fuhrgassl-huber.at
