  1. 1. Nutrient Retention in Constructed Wetlands

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johanna Kero; [2022]
    Nyckelord :Constructed wetlands; nutrient retention; phosphorus; nitrogen; catchment area factors; Anlagda våtmarker; näringsretention; fosfor; kväve; avrinningsområdesfaktorer;

    Sammanfattning : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. LÄS MER

  3. 2. Adaptation or Maladaptation? : A holistic approach to mangrove forestry to protect against climate change in Char Kukri Mukri, Bangladesh.

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Tilde Krusberg; Aisha Rahman; [2022]
    Nyckelord :mangrove forests; enrichment plantation; Bangladesh; climate change; climate adaptation; Nature-based Solutions.;

    Sammanfattning : Bangladesh is one of the most vulnerable countries to climate change, with coastal areas being especially vulnerable. Along the Bangladeshi coast lies mangrove forests that protect against storm surges, tropical cyclones, SLR, coastal erosion, and salt-water intrusion. LÄS MER

  4. 3. : Inverkan av släntnära portryck på släntstabilitet : En känslighetsanalys av siltslänter längs Ångermanälven

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Katia Calming; Myrna Öttenius; [2022]
    Nyckelord :Silt; slope stability; pore water pressure; SLOPE W; Ångermanälven; sensitivity analysis;

    Sammanfattning : The stability of natural slopes is goverened by many factors, one of which is the porewater pressure. In this study, a sensitivity analysis has been conducted in GeostudioSLOPE/W to investigate the impact of near-surface pore water pressure on thefactor of safety i silt slopes. LÄS MER

  5. 4. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Axel Barrdahl; [2022]
    Nyckelord :Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Sammanfattning : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. LÄS MER
