  1. 1. Kvillebäcken : analys och gestaltningsförslag - me[d]andra strukturer och processer

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Louise Stigsson Rigné; Emil Vernersson; [2024]
    Nyckelord :Urbanekologi; landskapsarkitektur; hydrologi; vattendrag; naturbaserade lösningar; blågrön infrastruktur;

    Sammanfattning : I byggandet av hållbara städer är utveckling av blågrön infrastruktur högaktuell, och inom detta faller stort fokus på utveckling av urbana vattendrags ekologi, vattenkvalitet, och förmåga att omhänderta konsekvenser av klimatförändringar. Få vattendrag uppnår miljökvalitetsnormerna, och platsspecifika utmaningar finns i varje vattendrag. LÄS MER

  3. 2. Sustainable Production Patterns for Hydropower Units

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Hannington Kayanja; [2023]
    Nyckelord :Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Sammanfattning : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. LÄS MER

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

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Ellen Lundin; Lovisa Liljenberg; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Talking Communities : Sámi Trail of Tears as a Model of Habitus-Based Reconciliation

    Master-uppsats, Uppsala universitet/Teologiska institutionen

    Författare :Janne Sirniö; [2023]
    Nyckelord :Truth Commissioning; Reconciliation; Forceful Displacement; Indigeneity; Slow Violence; Green Transition; Verdi System; Slow Tourism; Theory of Communicative Action;

    Sammanfattning : This conflict study in Theology investigates reconciliation possibilities in indigenous lands in northern Sweden to be discussed through the Sámi Trail of Tears Walking Trail – a real-life innovation project. The historical material is based on the depiction of forcefully dislocated Sámis and the now polarized situation where local indigenous groups risk new conflicts partly with each other, partly with extractive industries, motorized tourism, and the majority’s society.

  7. 5. Flood mitigation at catchment scale: assessing the effectiveness of constructed wetlands

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Elin Ekström; [2023]
    Nyckelord :Nature-based solutions; wetlands; catchment; performance indicators; flood management; hydrological modeling; SWAT; Naturbaserade lösningar; våtmarker; avrinningsområde; nyckelindikatorer; översvämningshantering; hydrologisk modellering; SWAT;

    Sammanfattning : Considering the potential for natural wetlands to store and retain water in the landscape,restored and constructed wetlands are increasingly implemented as Nature‐BasedSolutions (NBS) to mitigate downstream flooding. However, there is a frequent lack ofknowledge of the performance of NBS, and particularly wetlands, and how to best selectperformance indicators to measure their effectiveness. LÄS MER
