Exposed Geomembrane System at Großer Mühldorfer See Dam
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (6/2016)
Großer Mühldorfer See, a gravity dam owned by Verbund Hydro Power GmbH, will be part of Reisseck II pumped storage plant. The dam, 46.50 m high, has upstream prefabricated concrete slabs sealed with bituminous material and Kemperol strips requiring repeated repairs. A geomembrane system was installed to water tighten the dam and avoid maintenance. Among the challenges, the remote site location, the conditions of the facing and of the plinth, and the difficult climate. The article describes how design addressed such challenges and how installation was carried out to meet the objectives and deadlines.

Chambon dam: a Struggle against AAR
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (6/2016)
Chambon, a 137 m high concrete gravity dam completed in 1935, is affected by heavy AAR. A series of slot cutting and a drained exposed PVC geomembrane were completed in 1994 and provided an extension of service of 20 years. After new studies and the agreement of the authorities, EDF decided in 2013 to carry out new slot cutting, to reinforce the crown by a system of tendons and carbon bands and to install a new geomembrane.

Planning and Design of Kemah Arch Dam in a Very Strong Seismic Region
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (6/2016)
The Kemah arch dam is situated in Turkey close to the Eurasian Seismic Zone, where the peak ground acceleration of a 2 500-year earthquake reaches to a value of 0.70g. In this paper, the planning and design of the arch dam are reported besides presentation of main features of the project. Based on the results of geological and geotechnical investigation including the karstic foundation, shape of the arch dam was optimized using the time-history approach to cope with the extraordinary seismic loading, and the stresses in the arch dam and foundation were analysed in each time step. Based on the determined tensile and compressive stresses, the required concrete classes were accordingly defined.

The Contribution of Integrated Water Management to Achieving Environmental Protection and Sustainability Outcomes in the New Urban Areas of Melbourne, Australia
© DIV Deutscher Industrieverlag GmbH / Vulkan-Verlag GmbH (9/2012)
Achieving sustainable development continues to remain a priority for the governments of the world, especially in attempting to deal with population growth, increasing expansion of our cities, and climate change. Indeed, the Brundtland (1987) definition of sustainable development – to meet the needs of the present without compromising the ability of future generations to meet their own needs – has never seemed more urgent or more challenging. Water issues play a very key role in sustainable development, and as the United Nations Environment Program has commented, “water is not only the most basic of needs, but is also at the centre of sustainable development”.

Storage Management and Flood Warning in Urban and non-urban Drainage based on Runoff Prediction
© DIV Deutscher Industrieverlag GmbH / Vulkan-Verlag GmbH (8/2010)
Intense rainfall events are a major cause of flooding problems in urban and non urban areas. They are due to increased sealing of areas resulting in high runoff volumes. Especially in urban areas and small catchments the time interval between rainfall event and flood peak can be very short.

Drinking water policy
© Aristotle University of Thessaloniki (6/2009)
It is widely known that disinfection of drinking water is necessary to ensure clean water and safeguard the public from waterborne diseases such as typhoid, cholera, and dysentery. The most common disinfection practice is chlorination. For centuries it was considered as the safest disinfectant to protect the urban population from fatal diseases. In the decade of 1970 the first questions about the chlorination and its impact on human health was raised. After that, a bulk of literature has emerged and surveys have been carried out in order to investigate the possible effect of disinfection by-products (DBPs).

Uncertainty analysis of a municipal water distribution system
© Aristotle University of Thessaloniki (6/2009)
Uncertainty analysis of a municipal Water Distribution System (WDS) provides the basis for general model improvement in an efficient and economic way. The present work suggests a novel technique for such analysis, which is based on administering the hydraulic network solving routines of EPANET by a MATLAB code.

Qualitative vs. quantitative risk evaluation in contaminated sites management
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2006)
Decision analysis for contaminated sites management is generally carried out through a traditional engineering/economic point of view. However, new advances in risk assessment (e.g. probabilistic risk assessment), and the growing recognition and awareness of the importance of ’soft’, non-statistical, informal data in the decision-making process, require decision analysis methodologies that are capable of accommodating non-technical and politically biased qualitative information.
