  1. 11. 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. 12. Utökad utvärdering av CPTu-resultat

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ludvig Danfors; [2022]
    Nyckelord :Soil Behaviour Type; CPTu; CONRAD; signalbehandling;

    Sammanfattning : In Sweden, it is common to use the CPT - Cone Penetration Test when probing in loose soils. This is mainly because the method is suitable for further assessment of soil layer sequences, pore pressure and forming an estimate of the geotechnical properties in-situ. LÄS MER

  4. 13. : 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. 14. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Matilda Persson; [2022]
    Nyckelord :loess; origin; La Motte; XRF; Quaternary; weathering; climate; lössjord; ursprung; La Motte; XRF; kvartär; vittring; klimat;

    Sammanfattning : With our changing climate it becomes more vital to understand the processes that control climate change in order to better understand possible future shifts. By doing this, predictions can be made about future climates and better prepare us for them. LÄS MER

  7. 15. Loess in southwestern Sweden. Determining the genesis of the silt-rich layer rödfemman in Svartedalen nature reserve

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Fanny Ekström; Anna Hedeving; [2021-10-28]
    Nyckelord :Loess; silt; grain-size distribution; bimodal; Optically Stimulated Luminescence OSL ; p-XRF; spatial distribution; paleowind;

    Sammanfattning : The presence of loess in Sweden is relatively unexplored and has only been found in a few places. Loess acts as a paleoclimatic proxy, which in times of changing climates, is highly relevant. LÄS MER
