  1. 1. Lifetime CostEffectiveness of Constructed Wetland and Rain Garden Facilities in Relation to Expected  Treatment Performance

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Abdullah Noorhussin Ali; [2023]
    Keywords : Stormwater; Total cost; StormTac; Cost-effectiveness;

    Abstract : The purpose of this thesis is to investigate the cost effectiveness of two different stormwater control measure (SCM) facilities, namely a constructed wetland in Boden and a rain garden in Gothenburg (both Sweden), in relation to treatment efficiency and contributing catchment area. The study approach involved collection of data, construction, and maintenance activities with their respective costs, for the two stormwater control measures from commercial and literature data.

  3. 2. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Johanna Forss; [2023]
    Keywords : etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Abstract : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. READ MORE

    Keywords : Phosphorus; Arbuscular Mycorrhiza fungi; Saturated polonite; Nitrogen; Allium porrum; Sustainability; circular economy;

    Abstract : The continuous rise in global population continues to increase the demand for food. Meeting this rise in demand requires an increase in agricultural input, such as applying fertilizers, including phosphorus (P). READ MORE

  5. 4. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Adnan Asif Rifat; [2023]
    Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

  6. 5. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Laura Nina Bettoni; [2022]
    Keywords : denitrification; nitrate removal; temperature; woodchip bioreactor; waste rock leachate;

    Abstract : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). READ MORE
