    Author : Aleksander Jaworowski; [2022]
    Keywords : Manning’s coefficient; flow measurement; fish passage; fish migration; roughness coefficient; Technology and Engineering;

    Abstract : Fishway construction remains a crucial measure in environmental adaption of flow barriers. A well-functioning fishway should be able to pass all naturally occurring species of fish and other aquatic fauna. READ MORE

  3. 3. Quality and trust in physical model test : Examination by CFD modelling

    University essay from

    Author : Erik Kempe; [2022]
    Keywords : ;

    Abstract : Many of the hydropower dams in Sweden need to be refurbished in order to be able to handle higer design floods. A part of the work in refurbishing the dams is to build physical models. When the physical models are built the uppstream reservoir area is designed to be a couple of times wider and longer than the spillway. READ MORE

  4. 4. ADAPTED FISH FRIENDLY OPERATION OF SMALL-SCALE HYDROPOWER PLANTS : AN ECONOMIC ANALYSIS

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ana Gil Merino; [2022]

    Abstract : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.
