  1. 31. 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

  3. 32. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

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

    Author : Klara Yngve; [2022]
    Keywords : Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Abstract : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). READ MORE

  4. 33. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Emma Ryding; [2022]
    Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

  5. 34. SuDS water storage capacity calculator : A decision support tool for the implementation ofSustainable Drainage Systems in Östersund.

    University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Author : Tess van der Hulle; [2022]
    Keywords : Sustainable Drainage Systems SuDS ; Decision Support Systems DSS ; precipitation; calculator; stormwater model; Östersund; Sweden;

    Abstract : Heavy precipitation events are expected to increase in intensity and frequency, due to global warming. Sewer systems might overload during heavy rainfall, resulting in floods which potentially affect all municipalities in Sweden. READ MORE

  6. 35. Nutrient Retention in Constructed Wetlands

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE
