  2. 1. Sustainable snow handling

    Author : Karin Reinosdotter; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Urban snow contains pollution that originates from sources such as atmospheric precipitation, traffic emission, and de-icing chemicals. These pollutants accumulate in the snow during the winter and are released when the snow starts to melt. READ MORE

  4. 2. Snow deposit melt and atmospheric icing : analysis and modelling by weather station data

    Author : Eva Sundin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Snow deposit melt should be included when dealing with urban run off. Every winter structures experience atmospheric icing. The objective was to develop physically sound models based on weather station data for estimating snow melt and atmospheric icing. READ MORE

  5. 3. The Effect of Snow on Plants and Their Interactions with Herbivores

    Author : Mikaela Torp; Johan Olofsson; Christa Mulder; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Snow; arctic ecosystem; plant-herbivore interactions; phenology; nitrogen; phenolics; experimental manipulation; natural gradient; inter-annual variability; Biology; Biologi;

    Abstract : The ongoing climate changes are predicted to accelerate fast in arctic regions with increases in both temperatures and precipitation. Although the duration of snow cover is generally expected to decrease in the future, snow depth may paradoxically increase in those areas where a large amount of the elevated precipitation will fall as snow.

  6. 4. Estimation of snow wetness using multi-offset ground penetrating radar : towards more accurate estimates of snow water equivalent

    Author : Nils Granlund; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics; Applied Geology; Tillämpad geologi;

    Abstract : Measurements of snow water equivalent (SWE) constitute an important input to hydrological models used to predict snowmelt runoffs. The new generation of such models use distributed snow data, including distribution of SWE, as input, and rely on it for calibration and validation. READ MORE

  7. 5. Environmental occurrence and fate of semifluorinated n-alkanes and perfluorinated alkyl acids present in ski waxes

    Author : Merle M. Plassmann; Urs Berger; Michael McLachlan; Crispin Halsall; Stockholms universitet; []
    Keywords : Semifluorinated n-alkanes; Perfluorinated alkyl acids; ski waxes; snow; soil; fate; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Highly fluorinated organic compounds are emerging environmental contaminants of concern, due to their persistence, ubiquitous distribution, bioaccumulation potential and toxicity. Ski waxes are sources of highly fluorinated chemicals to the environment that have not been investigated so far. READ MORE
