  1. 16. Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Martin Larsson; [2019]
    Keywords : soil solute vertical transport modelling vadose; Earth and Environmental Sciences;

    Abstract : This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. READ MORE

  3. 17. Spreading of microplastics from artificial turf via stormwater

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Johanna Lundström; [2019]
    Keywords : Microplastics; Artificial turf; Granule trap; Granulate; Waterflows; mikroplast; konstgräsplan; granulatfälla; granulat; vattenflöden;

    Abstract : På senare tid har mikroplaster i hav och sjöar uppmärksammats som ett potentiellt stortmiljöproblem. Idag finns mikroplaster spridda över hela världens vatten från polerna till ekvatorn.År 2016 uppmärksammades konstgräsplaner som den nästa största källan till spridning avmikroplaster till sjöar och vattendrag i Sverige [1].

  4. 18. Nutrient concentrations before and after the Focus on Phosphorus project in E23 catchment

    University essay from SLU/Dept. of Soil and Environment

    Author : Åsa Larsson; [2018]
    Keywords : phosphorus; Greppa fosforn; two-stage ditch; structure liming; sedimentation pond;

    Abstract : Between 2007-2014, as part of the Greppa Näringen, there was a subproject on phosphorus losses called Focus on Phosphorus (FoP; Greppa Fosforn). Previous measures on eutrophication mainly focused on nitrogen leakage, whilst the purpose of FoP was to test already known mitigation methods against phosphorus losses in the field. READ MORE

  5. 19. Small-Scale Biogas Upgrading System Modeling Tool Development

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : David Saldarriaga; [2018]
    Keywords : ;

    Abstract : The potential of biogas to decarbonize society depends partially on the success of small-scale systems. Two specific locations where biogas units can be implemented are considered in this study: small farms and small isolated populations. READ MORE

  6. 20. Forest drainage effects on tree growth in Northern Sweden : developing guidelines for ditch network maintenance

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Hanna Glöd; [2018]
    Keywords : ditch cleaning; ditch network maintenance; drainage effect; forest drainage; indicators; dikningseffekt; dikesrensning; dikesunderhåll; indikatorer; skogsdikning;

    Abstract : At present, there are no clear guidelines for when and where ditch network maintenance (DNM) should be performed in Sweden. Recently there have been attempts to create tools that indicate the need for DNM, one of these tools is the Ditch Flow Tracker (DFT). READ MORE
