  • Cumulative Environmental Impact Of Cascade Hydropower Dams Construction On The Water-River

    Abstract Variation of environmental indices in cascade dams could be intensified in comparison with single dams. In cascade dams the intensification of long term negative impacts are more important than the impacts in single case dam. In addition, these impacts are more permanent and intense, so the precise study of cascade dams is indispensable. The main goal in this research is to study the ...

  • How to plan hydropower stations for the future

    The hydropower plants of tomorrow won’t only produce energy. Constructing dams will also provide new drinking water sources, irrigation for crops, and new waterways for transport. In the words of most of the scientists here at World Water Week in Stockholm, Sweden, they will be ‘multipurpose’. This means that each plant ...

  • 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 ...

  • Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power

    Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement ...

  • 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 ...

  • 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 ...

  • An assessment of reservoir filling policies for the Grand Ethiopian Renaissance Dam

    Africa's largest hydropower facility is currently under construction on the main stem of the Blue Nile River in Ethiopia. The Grand Ethiopian Renaissance Dam (GERD) is poised to facilitate regional development with a 63 billion cubic meter reservoir and 6,000 MW of power generating capacity. To date, however, no reservoir filling rate policy has been established. This policy will have ...

  • The Grand Renaissance Dam and prospects for cooperation on the Eastern Nile

    The escalation of tensions between Ethiopia and Egypt over the construction of the Grand Renaissance is at least partly based on a misunderstanding of the nature of the risks this dam poses to Egypt. There is a two-part, win–win deal that can defuse tensions between Egypt and Ethiopia. First, Ethiopia needs to agree with Egypt and Sudan on rules for filling the Grand Renaissance Dam (GRD) ...

  • Understanding India-Pakistan water politics since the signing of the Indus Water Treaty

    On 19 September 1960, the Indus Water Treaty (IWT) was signed between India and Pakistan, presumably resolving the conflict of Indus water sharing. Nevertheless, over the years the conflict has re-appeared, dragging both the riparian states into confrontation. This paper explores the reasons that lead to conflict despite the Indus water sharing having already been resolved by the IWT. Analysis ...

  • Analysis of Development Course of Artificial Sand Making Technique

    In the artificial sand and stone material production system, the sand making technology is one of the most important technologies, and the sand making equipment is the most equipment because the performance of the sand maker and the reasonability of the sand making technology influence the investment of the whole artificial sand and stone material processing system and the quality of the ...

  • Chile Renewables Report Q1 2013

    We have downgraded our non-hydropower renewable generation growth forecast for 2013 from 6.2% to 5.6% due to new data from the government. Conversely, we have revised up our long-term growth forecast from 5.5% to 6.3%, due to our expectations of economic growth and the country’s current power situation. That said, we note that economic viability could be lacking in many renewable energy ...


  • The Sri Lanka environmental flow calculator: a science-based tool to support sustainable national water management

    As Sri Lankan water resources are being increasingly exploited, particularly for hydropower and irrigation, ecologists, water practitioners and policymakers alike are realizing the importance of protecting these resources and setting environmental sustainability thresholds. Environmental flows (EF) – the concept that helps define such thresholds – has now become an integral part of ...
