  1. 1. Natura 2000-områdens roll i omprövningen av vattenkraftens miljötillstånd

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Frida Larsson; [2024]
    Nyckelord :Vattenkraft; Natura 2000; miljötillstånd; miljöåtgärder; nationell plan; elproduktion; reglerförmåga; GIS-analys; Technology and Engineering;

    Sammanfattning : Vattenkraften utgör ungefär 45 % av Sveriges elproduktion och har varit en stabil energikälla med lågt koldioxidutsläpp under lång tid. Med ett allt större inslag av intermittenta energislag i elsystemet, fyller vattenkraften också en viktig funktion med sin reglerförmåga för balansering. LÄS MER

  3. 2. Sensitivity of Norway Spruce (Picea abies) to inundation.

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Whitney Cleopatra Vlahakis; [2023]
    Nyckelord :Inundation; riparian zone; spruce seedlings; restoration; mortality;

    Sammanfattning : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. LÄS MER

  4. 3. Determination of a hydropower "go-to area" : Klarälven and Dalälven potential assessment and environmental regulation constraints

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Paula Aparicio Garcia; [2023]
    Nyckelord :Hydropower; REPowerEU; Go-to areas; GIS; MCDA; AHP; RED II; WFD; Nature 2000; Vattenkraft; REPowerEU-Planen; Go-to area; GIS; MCDA; AHP RED II; WFD; Nature 2000;

    Sammanfattning : The current energy crisis with sky-rocketed prices has created the need for new sustainable solutions in the energy production sector. The REPowerEU Plan, presented by the European Commission, has taken up on this and has established measures to accelerate the introduction of new renewable energy capacity in Europe, such as the designation of “go-to areas” by Member States to shorten authorization permits in areas with high potential and low environmental impacts.

  5. 4. Evaluation of restoration efforts in Dalälven - conditions for survival rate of Salmo trutta and Salmo salar

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ville Svärd; [2023]
    Nyckelord :Restoration; river; salmonids; benthic fauna;

    Sammanfattning : Rivers are among the most anthropogenically affected ecosystems in the world by irrigation, transportation, channelizing, and hydropower. Habitat restorations have become a popular method to restore the heterogeneity and complexity of rivers aiming for improvement of biodiversity. LÄS MER

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

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Xuan Ye; [2022]
    Nyckelord :river space; municipal nature reserve; ecological restoration; landscape planning; fish migration passage; human recreation;

    Sammanfattning : The natural environment and ecological services of rivers and the needs and expansion of human activities using rivers causes conflicting interests. Human survival is inseparable from the dependence on the natural environment, but at the same time, the continuous demand for natural resources has also caused an irreversible impact. LÄS MER
