  1. 11. Effects of summer peaks on brown trout and Atlantic salmon growth and survival in hydropower-regulated Gullspång River

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Oscar Hallberg; [2023]
    Keywords : hydropeaking; hydropower; fish; salmon; salmo salar; salmo trutta; summer; survival; growth; parr; fry; korttidsreglering; vattenkraft; salmonid; salmo salar; salmo trutta; tillväxt; överlevnad; lax; öring;

    Abstract : Daily demands for electrical power are met through sub-daily release of turbined water in the form of hydropeaking. Hydropeaking’s changes to stream flow are listed as a threat to biodiversity in river ecosystems as it causes rapid habitat alteration such as increased depth and velocity, affecting the species living downstream.

  3. 12. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Ellen Lundin; Lovisa Liljenberg; [2023]
    Keywords : LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Abstract : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. READ MORE

  4. 13. Pilot Study: Test Rig for Self-lubricating Kaplan Runner Bearings

    University essay from KTH/Skolan för industriell teknik och management (ITM)

  6. 15. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

    University essay from Uppsala universitet/Datalogi

    Author : Lovisa Olsson; Julia Hellström; [2023]
    Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

    Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE
