  1. 11. Future trends in urban stormwater quality : effects of changes in climate, catchment characteristics and processes and socio-economic factors

    Författare :Matthias Borris; Lian Lundy; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Climate change and progressing urbanization cause numerous environmental concerns, including the impacts on urban drainage. Such impacts were addressed during the last two decades with focus on hydraulic overloading of drainage systems and the means of overload remediation by stormwater management. LÄS MER

  3. 12. Influential factors in simulations of future urban stormwater quality : Climate change, progressing urbanization and environmental policies

    Författare :Matthias Borris; Tone Merete Muthanna; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Climate change is regarded as one of the main future challenges implyingchanging hydrological conditions in urban areas. At the same time many urbanareas are expected to grow due to increasing population, which will most likelycause a higher level of urbanization. LÄS MER

  4. 13. Hydrological modelling of green urban drainage systems : Advancing the understanding and management of uncertainties in data, model structure and objective functions

    Författare :Ico Broekhuizen; Maria Viklander; Günther Leonhardt; Jörg Rieckermann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : The use of green urban drainage systems such as green roofs, swales and pervious areas has in recent years become a popular option to reduce flood risk and water quality problems in a more sustainable way than with traditional pipe-based drainage systems. Computer models are valuable tools for the management of such systems. LÄS MER

  5. 14. Uncertainties in rainfall-runoff modelling of green urban drainage systems : Measurements, data selection and model structure

    Författare :Ico Broekhuizen; Maria Viklander; Günther Leonhardt; Manfred Kleidorfer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Green urban drainage systems are used to avoid flooding and damages to people and property, while limiting the downstream flooding and water quality problems caused by pipe-based drainage systems. Computer models are used to analyse and predict the performance of such systems for design and operation purposes. LÄS MER

  7. 15. Grassed swales for urban storm drainage

    Författare :Magnus Bäckström; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : This thesis investigates the environmental, economic and functional aspects of using grassed swales for the conveyance and treatment of stormwater. A grassed swale is a shallow, grass-lined channel. LÄS MER
