  1. 1. 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

  2. 2. Water sources' key role in the Vomb basin biosphere reserve. An analysis of ecosystem services.

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Ousayma Bakir; [2022]
    Keywords : Ecosystem services analysis; biosphere reserve; water sources; classification; Vomb; Skåne; south of Sweden.; Earth and Environmental Sciences;

    Abstract : This study was done to gain an understanding of the importance of 12 water sources that are in the Vomb biosphere reserve. To do so, an ecosystem services analysis that included the four following types of ecosystem services: provisioning, supporting, regulating, and cultural services, was conducted. READ MORE

  3. 3. 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

  4. 4. 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

  5. 5. A preliminary study of evidence-based tool for wetland optimization - A case study using QSWAT+

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära
