To address the water-related issues faced by humans, planning and construction of dams, water diversion projects, other infrastructures have been continuously adopted decision makers worldwide. This is especially case for Yalong River Basin (YRB) in China, which expected to be one most regulated rivers due reservoir planned South-to-North Water Diversion project. understand potential impact the...

1 Securing the supply and equitable allocation of fresh water to support human well-being while sustaining healthy, functioning ecosystems is one of the grand environmental challenges of the twenty-first century, particularly in light of accelerating stressors from climate change, population growth and economic development. Rehabilitation of ageing infrastructure and construction of new infrast...

Abstract. The improvement of a forecasting system and the continuous evaluation its quality are recurrent steps in operational practice. However, systematic forecast value or usefulness for better decision-making is less frequent, even if it also essential to guide strategic planning investments. In hydropower sector, several systems use medium-range hydrometeorological forecasts (up 7–10 d ahe...

Sediment erosion not only reduces efficiency and life of hydropower turbines but also causes problems in operation and maintenance. Several factors are responsible for this erosion in hydro turbine components. This paper presents the sediment erosion types in hydraulic turbines and their components based upon an extensive literature review and the field observation at Cahua hydropower plant, Pe...

The interbasin water transfer is a remedy to mitigate the negative issues of water shortage in arid and semi-arid regions. In  a water transfer project  the receiving basin always  benefits while, the sending basin may suffer. In this study, the project of interbasin water transfer from Dez water resources system in south-west of Iran to the central part of the contrary is  investigated during...

Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7340-4 This thesis addresses the economic trade-offs between hydropower and fish production, based on an empirical assessment of the costs and benefits of changin...

We present a cost-benefit framework to analyze the interaction between hydropower and salmon in a dynamic context. The framework is used to derive cost-benefit rules for projects that affect wild salmon survival. Our approach is illustrated with data from an ongoing project regarding a potential salmon passage-hydropower conflict in the northern Swedish river Umeälven and its largest salmon pro...
