  1. 1. Clear-cut Effects on Snow Accumulation and Evapotranspiration in a Boreal Catchment in Northern Sweden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Mikaela Rudling; [2013]
    Nyckelord :: Clear-cut; HBV; boreal forest; runoff; evapotranspiration; snow accumulation; avverkning; HBV; avrinning; evapotranspiration; snöackumulering;

    Sammanfattning : The aim of this thesis was to investigate the processes behind an unexpected runoff behaviour after a clear-cut in a boreal forest in northern Sweden (Balsjö). The risks of increased flooding, erosion, nutrient leakage and changes in the local ecosystems are some reasons why it is important to fully understand the effect of clear-cuts on the water balance.

  3. 2. Factors controlling the temporal variability of mercury in runoff from seven catchments in Northern and Southern Sweden

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Andrea Kraus; [2011]
    Nyckelord :Total Mercury; Methylmercury; Flow; Temperature;

    Sammanfattning : The increased input of anthropogenic mercury in the environment has led to the accumulation of mercury (Hg) in the aquatic food chain and poses serious problems to the ecosystem and human health. Time series data from May 2004 – May 2010 in three catchments in northern (Balsjö) and from October 2006 – 2009 in four catchments in southern (Örebro) Sweden associated with different forest treatments (e.

  4. 3. Skogsavverkningens påverkan på grundvattnets flödesvägar

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Emil Vikberg; [2010]
    Nyckelord :Grundvatten; avverkning; flödesvägar;

    Sammanfattning : I Sverige avverkas stora mängder skog varje år vilket ger stora skogsområden som är heltkalhuggna. Avverkning av skogen leder till att evapotranspirationen och interceptionen frånväxter minskar. Detta ger en ökad grundvattenbildning som i sin tur leder till en ökad avrinning i vattendragen som avvattnar de avverkade skogsområdena. LÄS MER

  5. 4. The effect of forest cover for the dynamics of a snowpack : linking snow water equivalents, meltwater contributions and evaporative loss

    Magister-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Álvaro Valle Millán; [2010]
    Nyckelord :Forest hydrology; Clearcut; Snow accumulation; Snow water equivalents; Meltwater released; Evaporative loss; Water balance;

    Sammanfattning : Forestry is one of the main economical activities in Sweden, but it can seriously affect the dynamic of the water cycle by altering several hydrological factors such as timing and amount of snow melt and meltwater contributions from the snowpack to the soil.This thesis, performed during the spring 2010 within the “Balsjö Catchment Study” in Northern Sweden, was carried out in order to understand how forest cover can influence the hydrology of snow-dominated boreal catchments.

  7. 5. Effects of forest harvesting on the hydrology of boreal streams : the importance of vegetation for the water balance of a boreal forest

    Magister-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Lenka Kuglerová; [2010]
    Nyckelord :Water balance; clear cutting; forestry; runoff dynamic; evapotranspiration; snow accumulation;

    Sammanfattning : Forestry is one of the main industries in Scandinavia but also timber harvesting can have a large impact on the ecology and hydrology of boreal forests. The removal of the forest canopy alters many variables in the catchments such a snow accumulation, timing of the snow melt, evapotranspiration, interception loses and soil characteristics. LÄS MER
