  1. 1. Environmental impact of peat mining : Development of storm water treatment methods

    Författare :Bjørn Kløve; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. LÄS MER

  3. 2. Methane exchange in a boreal forest: : the role of soils vegetation and forest management

    Författare :Elin Sundqvist; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chamber measurements; gradient measurements; clear-cut; topography; water table depth;

    Sammanfattning : Popular Abstract in English Forests have a positive impact on the level of greenhouse gases in the atmosphere because they absorb carbon dioxide through photosynthesis and store carbon in the soil. Moreover, many forests function as a sink for the greenhouse gas methane (CH4). LÄS MER

  4. 3. Topographic Control of Groundwater Flow

    Författare :Lars Marklund; Anders Wörman; Shulan Xu; Roy Haggerty; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Modeling; Topography; Spectral analysis; Fourier series; Exact solu-tions; Multi-scale; Grundvatten; Modellering; Topografi; Spektralanalys; Fourier serier; Analytisk lösning; Flerskalig; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

    Sammanfattning : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow.  The groundwater table defines the distribution of the potential energy of the water. LÄS MER

  5. 4. Local Environment at Stake : The Hallandsås Railway Tunnel in a Social and Cultural Context

    Författare :Annelie Sjölander-Lindqvist; Humanekologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydraulic engineering; offshore technology; soil mechanics; Civil engineering; ethnology; Cultural anthropology; groundwater; environmental impact; landscape; Facility siting; local community; Hallandsås railway tunnel; Väg- och vattenbyggnadsteknik; etnologi; Kulturantropologi;

    Sammanfattning : A major trend in facility siting research focuses on economic and psychological aspects of land-use regarding the location of potentially hazardous technological facilities including storage for high-level radioactive waste, landfills, chemical plants, large-scale dams, or waste incinerators. Such facilities frequently have profound environmental impact and are often understood by local citizens as intrusions on their environment that threaten landscape, place, and community. LÄS MER

  7. 5. A multidisciplinary approach: geophysics, hydrochemistry and hydrometeorology for addressing water security in semiarid alluvial fans

    Författare :Andres Gonzales; Teknisk geologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysical methods; Hydrochemistry; Hydrometeorology; Bolivia; Alluvial fan;

    Sammanfattning : Water security offers to the local population an adequate quality and quantity of water for health, economy, livelihoods and ecosystems. Hence, achieving basic levels of water security should be a priority in areas where access to fresh water is scarce. LÄS MER
