  1. 11. Seasonal variation of road runoff in cold climate

    Författare :Camilla Westerlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The main objective of this thesis was to characterize and study the behaviour and transport of pollutants, i.e., suspended solids, particles and heavy metals, in road runoff from a small urban catchment during snowmelt and rainfall. LÄS MER

  2. 12. Biofiltration technologies for stormwater quality treatment

    Författare :Godecke-Tobias Blecken; Jean-Luc Bertrand-Krajewski; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Due to high runoff volumes and peak flows, and significant contamination with (inter alia) sediment, metals, nutrients, polycyclic aromatic hydrocarbons and salt, urban stormwater is a major cause of degradation of urban water ways. Since current urban drainage systems, which heavily rely on piped sewer networks, may not be sustainable, attempts are being made to develop and refine sustainable urban drainage solutions, notably in Water Sensitive Urban Design (WSUD) and Low Impact Development (LID) concepts.

  3. 13. Porous pavement in a cold climate

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

    Sammanfattning : Local disposal of stormwater can be achieved by using porous pavements instead of impermeable pavements with conventional stormwater pipes and manholes. The objective of this thesis was to analyse the performance of porous pavements during freezing, thawing, and snowmelting conditions in order to evaluate if the porous pavement is suitable for stormwater management and road construction in cold climate regions.
