  1. 6. 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

  3. 7. 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

  5. 9. Våtmarksbatymetri : djupmätning av 10 anlagda våtmarker i Mälardalen

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Gordon Lindau; [2022]
    Keywords : batymetri; djupmätning; portabelt ekolod; kastbart ekolod; våtmark; fosfordamm;

    Abstract : Tio anlagda våtmarker i jordbrukslandskap i Mälardalen har undersökts i syfte att bestämma vattendjup och volym samt för att studera batymetriska metoder som kan vara lämpliga vid djupmätning av fosfordammar och andra grunda våtmarker. De metoder som använts är portabelt, kastbart ekolod som både släpats bakom kajak och kastats med fiskespö från land samt manuell mätning med mätsticka. READ MORE

  6. 10. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christian Lundström; [2022]
    Keywords : Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

    Abstract : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. READ MORE
