  1. 1. Adsorption of dissolved organic matter in aquatic ecosystems : Effects on composition and reactivity

    Författare :Marloes M. Groeneveld; Lars Tranvik; Dolly Kothawala; Suzanne Tank; Uppsala universitet; []
    Nyckelord :dissolved organic matter; DOM; carbon; aquatic; adsorption; mineral particles; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Inland waters receive organic matter from terrestrial ecosystems and in situ production. In transit from land to the ocean, dissolved organic carbon (DOC) may be mineralised to inorganic forms (CO2 and CH4) by microbial degradation and photodegradation. LÄS MER

  3. 2. Nitrogen Removal in Created Wetlands : Considerations – Challenges – Possibilities

    Författare :Josefin E. Nilsson; Antonia Liess; Stefan Weisner; Eva Lindström; Jennifer Tank; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; eutrophication; constructed wetlands; agricultural runoff; denitrification; wetland multifunctionality; climate change; nutrient retention; vegetation; hydrology; greenhouse gas emissions; biodiversity; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Created wetlands in agricultural landscapes deliver a multitude of ecosystem services, one of which is the removal of nitrogen (N) from water to reduce eutrophication. Wetland N removal, primarily through denitrification, is influenced by various factors. LÄS MER

  5. 4. Three-Dimensional Simulation and Physical Modelling of Flows in Detention Tanks - Studies of Flow Pattern, Residence Time and Sedimentation

    Författare :Åsa Adamsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tracer study; pond; numerical simulation; particle tracking; CFD; bed shear stress; storage tank; stormwater; detention tank; flow pattern;

    Sammanfattning : Improving effluent water quality to receiving waters using stormwater ponds and storage tanks is acknowledged to be an effective method. The performance of the method depends however on flow conditions such as velocity distribution, short-circuiting currents and the volume through which the influent water flows, the so called effective volume.
