  1. 26. Population dynamics of the horned grebe in constructed wetlands in Östergötland.

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Johanna Pellnor; [2021]
    Nyckelord :Biodiversity; Canadian pondweed; Common roach; Horned grebe; Pike; Population dynamics; Wetland;

    Sammanfattning : The population size of the horned grebe, Podiceps auritus, is declining in most of the world due to loss of wetlands, deteriorating water quality and establishment of predatory fish such as pike, Esox lucius, in former fish free wetlands. The horned grebe is now globally classified as vulnerable. LÄS MER

  3. 27. Sustainable stormwater management in Stockholm's inner city

    Kandidat-uppsats, KTH/Urbana och regionala studier

    Författare :Nils Brattgård; [2021]
    Nyckelord :Stockholm; Sustainable Stormwater Management; Stormwater; Runoff; Green Infrastructure; Structural Soil; Trees; Constructed Wetlands; Wet pond; Green roof; Green wall; Institutional challenges; Technical challenges;

    Sammanfattning : Much like other cities Stockholm has traditionally used a technical system for managing stormwater. With time this system has become overburdened and has led to large environmental concerns. To reach water quality goals set by the EU Stockholm needs to decrease pollution released to recipients by 70-80%. LÄS MER

  4. 28. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Hani Yahya Ali Shubail; [2020]
    Nyckelord :Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

    Sammanfattning : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. LÄS MER

  5. 29. Water quality and water availability at Gårdstånga Nygård

    Kandidat-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Lina Lennklev; [2020]
    Nyckelord :Water resource management; Water quality; Agriculture; Water balance; Constructed wetlands; Surface water bodies; Technology and Engineering;

    Sammanfattning : The report investigated partly how agriculture on and near Gårdstånga Nygård affected the water quality in nearby surface water bodies during the period of testing, and partly whether the supply of water in the Rödabäck river basin is large enough to enable the construction of a well-functioning irrigation pond. The water quality was evaluated by collecting water samples in the field, reading the values of these samples for various water quality parameters and finally an evaluation of said values. LÄS MER

  7. 30. Kolbestånd i restaurerade våtmarker, En fältstudie av anlagda våtmarker i Lunds kommun

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Simon Lin; [2020]
    Nyckelord :Kolbestånd; kolhalt; kolinlagring; kolsänka; sediment; våtmark; Earth and Environmental Sciences;

    Sammanfattning : Sedimentation of organic carbon in shallow lakes and wetlands removes CO2 from the atmosphere and can be considered a natural carbon sink. Actions toward regulating restored wetlands as carbon sink would provide Lund municipality with solution to combat CO2 emission goals for the future. LÄS MER
