  • Health and environmental impacts of the hydroelectric fuel cycle

    The impacts on health and the environment and the associated damage costs caused by the hydroelectric fuel cycle are assessed in this paper. To this purpose, a large hydroelectric project along the Nestos river in northern Greece has been selected as an example. A large number of impacts have been identified. Occupational accidents, impacts on agriculture and forests, noise produced during the ...

  • INSPECTION and Continuous Quality Surveillance during the construction of hydroelectric powerplants. Published in International Water Pow

    During the construction of hydroelectric plants, poor quality can have a hugely negative impact on construction time, on plant performance and on safety. INSPECTEAM Hydro has developed a method known as the Continuous Quality Surveillance Scheme (CQSS). The article describes the method to minimize the Cost of Poor Quality (COPQ) and to ensure the best quality performance during the ...

  • Continuous Quality Surveillance Scheme to minimize the Cost Of Poor Quality in the construction of hydroelectric powerplants - IDRA 2012

    During the construction of hydroelectric plants, poor quality can have a hugely negative impact on construction time, on plant performance and on safety. We propose a method of keeping under control the manufacturing of the most critical components, such as pressure parts, rotors and valves, with a view to minimizing the Cost of Poor Quality (COPQ). This method is known as the Continuous Quality ...

  • Monitoring greenhouse gas emissions from hydroelectric reservoirs in northern Quebec, Canada

    Surface waters of natural freshwater bodies are capable of releasing far more carbon into the atmosphere than they absorb (Cole et al. 1994). Artificial reservoirs are also known to have environmental impacts which include greenhouse gas (GHG) emissions (Rosenberg et al. 1997, Fearnside et al. 2004, Tremblay et al. 2005). Therefore the inclusion of hydroelectric facilities as part of an overall ...

  • 1997 IFAI award devil Canyon hydroelectric power plant, San Bernardino, California

    Constant demands for water and electricity in heavily populated areas in California prompted the Devil Canyon Power Plant project. Constructed from 1969 to 1974, the power plant is located at the San Bernardino Mountains near the mouth of Devil Canyon. With two pipelines carrying water from Silverwood Lake, an elevation drop of almost 1500 ft (460 m) between the lake, and four Pelton wheel ...

  • Evaluation of melioration area damage on the river Danube caused by the hydroelectric power plant ‘Djerdap 1’ backwater

    Construction of the hydroelectric power plant (HPP) ‘Djerdap 1’ formed a backwater effect on the Danube and its tributaries, which had an inevitable influence on groundwater level, causing it to rise and thus creating additional threats to all melioration areas on more than 300 km of the Danube riversides, as well as on the riversides of its tributaries: the Sava (100 km) and the ...

  • The influence of climate and dam construction on the Ibera wetlands, Argentina

    Abstract  The purpose of this work is to assess the impact on the Esteros del Ibera wetland ecosystem caused by the Yacyreta dam, a large hydroelectric power plant on the Parana River, Argentina, in comparison to other factors of environmental change. The project of the dam started around 1970. The power plant began operating in 1994. In 1989, the neighboring Ibera wetland ecosystem showed ...


  • Case Notes: Privy to Unsustainable Arguments in the Belize Dam Case

    It is fair to say that the heydays of gigantic hydroelectric projects are numbered. First, in Europe, the optimum for hydroelectricity has been reached as all the major water sources have already been harnessed. The ‘dash for gas’ soon after privatisation and restructuring in the early 1990s has also contributed to the decline in interest in exploring hydroelectricity. Further still, ways are ...

  • Risk sharing in hydropower development: case study of the Chukha Hydel Project in Bhutan

    The Himalayan rivers have an enormous hydropower potential that is still not exploited fully for the benefit of the region. Bhutan and Nepal together have an economically feasible potential of 60,000 MW of hydroelectric power generation capacity but are too weak financially to bear the risks associated with the development of their hydro resources alone. India is the only potential market for ...

  • Article: Reconciling renewable energy and the local impacts of hydro-electric development

    The UK and Scottish governments’ policy commitments to renewable energy, driven by recognition of the impacts of global warming and climate change, have led to increasing interest in all aspects of renewable energy. This article is concerned with how the Scottish Executive is able to reconcile new hydro-electric developments as a source of renewable energy with the local impacts of those ...


  • Institutional evolution of Missouri river management

    The Missouri River is the longest river in North America and flows from the semi-arid western states to the relatively moist Midwest. An integrated system of large reservoirs, constructed in the mid-20th century, provides important water storage, hydroelectricity and flood control benefits. This system has been managed by the US Army Corps of Engineers which has traditionally followed its ...

  • Understanding water-society nexus: insights from Turkey's small-scale hydropower policy

    Turkey's recent venture involving the construction of hundreds of small-scale hydropower projects is a significant trend, both in regard to its contribution to Turkey's hydroelectricity production and the social and environmental impact of these projects at the local level. Turkey's hydropower policy was premised on a conventional understanding of water driven by science, technology, and the ...

  • Iberdrola to build nine wind farms in Brazil

    Spain’s Iberdrola Renovables and its Brazilian partner, energy company Neoenergia, have received a contract from Brazil’s Agencia Nacional de Energia Electrica (Aneel) to deliver the electric output of nine wind farms—a deal characterized as a major step in allowing the Iberdrola-Neoenergia consortium to move ahead with construction of the facilities. The nine wind ...

  • Railroad track ballast crushing and screening plant

    Track ballast forms the track bed upon which railway sleepers (UK) or railroad ties (US) are laid. It is packed between, below, and around the ties. It is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials. The crushed stone comes from the stone crushing and screening plant, and DSMAC supply high efficiency railroad track ballast crushing ...

  • Snoqualmie falls riverbank stabilization case study

    Puget Sound Energy - Snoqualmie Falls Redevelopment Project In 2009, PugetSound Energy began a comprehensive upgrade of the hydroelectric infrastructure at Snoqualmie Falls - a power generation facility built in 1890. Loose soils and heavy rainfall contributed to a landslide along the Snoqualmie River bank in the Fall of 2010, and GeoEngineers was commissioned to provide a long-term design ...

  • Nation Building

    Will Canada bond together as one happy family to build an east-west transmission grid to carry energy to one and all? Is it even a good idea? Just over 120 years ago this country was bounded together by Sir John A. MacDonald’s national dream of a transcontinental railway. Now some politicians are promoting another national dream – the construction of an east-west transmission grid that would meet ...

  • Can Lao PDR learn from its neighbors mistakes and develop sustainably?

    The Lao People’s Democratic Republic is among the poorest, least developed countries in Asia with an estimated Gross Domestic Product (GDP) of $1900 per capita in 2007 and agriculture as the main economic activity. The Asian Development Bank is nevertheless positive about the country’s economic outlook due to increases in new foreign investment and government-led initiatives in hydropower, food ...
