  1. 1. Adaptive Fishway Design : Designing a Bypass Channel to Fit Large Discharge Fluctuations

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Melina Sattelmeier; [2023]
    Keywords : ;

    Abstract : Especially with regard to achieving the goals of the European Water Framework Directive, the construction of fishways is becoming more prominent in Sweden's hydraulic engineering sector. Particularly the importance of nature-like bypass channels is increasing, being the type of fishway that is currently implemented in most cases of small scale hydropower. READ MORE

  3. 2. Fish Friendly Turbines forDownstream Migration : Literature review and case studies

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Signe Rosenblad; [2023]
    Keywords : Downstream passage solutions; downstream migration of fish; small-scale hydropower; eel; trout; Nedströms passagelösningar; nedströms vandring av fisk; småskalig vattenkraft; ål; öring;

    Abstract : As the energy consumption is constantly increasing, the demand of renewable energy is increasing too. Thirtythree percent of the renewable energy production in Europe constitutes of hydropower. Hydropower is animportant energy source as it has stabilizing and storing functions, but it heavily affects biodiversity. READ MORE

  4. 3. Evaluating an increased spill regime as a management tool to improve downstream passage of salmon smolt

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Mattias Hansson; [2022]
    Keywords : hydraulic modeling; hydroacoustic telemetry; time to event analysis; hydraulisk modellering; överlevnadsanalys; hydroakustisk telemetri;

    Abstract : The anadromous Atlantic salmon (Salmo salar) is dependent on river connectivity to reach spawning and rearing habitats in rivers. Most rivers are today fragmented by artificial barriers such as hydroelectric powerplants (HEP) which impede this migratory movement. READ MORE

  5. 4. Manning’s roughness coefficient in small scale nature-like fish passages

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    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

  6. 5. To create multifunctional riverscapes : the example of Älvkarleby in the Nedre Dalälven River, Sweden

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Xuan Ye; [2022]
