  1. 11. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Per Wahlquist; [2023]
    Keywords : volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Abstract : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

  3. 12. Treatment of Metals in Highway Runoff Water : Comparison of green infrastructures and filter material for stormwater treatment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fanny von Matérn; [2023]
    Keywords : Road runoff; heavy metals; constructed wetland; stormwater pond; vegetated filterstrip; vegetated swale; sandfilter; reactive filter material; Vägdagvatten; tungmetaller; anlagd våtmark; dagvattendam; översilningsyta; svackdike; sandfilter; reaktiva filtermaterial;

    Abstract : Highway runoff transport high concentrations of heavy metals. As climate change affect the environment with for example increased storm events, the treatment of road runoff becomes more important. READ MORE

  4. 13. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Margot Jeanne Knapen; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Abstract : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. READ MORE

  5. 14. Constructed wetland for post-treatment of phosphorus in wastewater : An initial assessment of potential design and application to a small-scale water treatment plant in Åre municipality, Sweden

    University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Author : Johan Arnemo; [2023]
    Keywords : : cold climate; ecological engineering; free water surface wetland; horizontal subsurface wetland; phosphorus treatment;

    Abstract : In recent years, the treatment of phosphorus in Nyland's water treatment plant (located in Åre municipality) has been substandard. The problem has persisted despite attempts to lower the concentration to meet the emission requirements. READ MORE

  6. 15. Flood mitigation at catchment scale: assessing the effectiveness of constructed wetlands

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE
