  1. 1. Lake Hydrodynamics and Pollution Transport under Climate Change : The Case of Lake Victoria

    Författare :Seema Paul; Henrik Ernstson; Zahra Kalantari; Abhijit Mukherjee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bathymetry mapping; model verification; water balance; correlation; tracer transport; wind hydrodynamics; pollution and nutrient transport; climate effect; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : A very small part of the total earth’s water is freshwater (only 2.5 %). Unfortunately, due to climate change and pervasive manmade activities, surface freshwater quality in many places of the world has become degraded. LÄS MER

  3. 2. Impacts of land use change on river streamflow and water quality in a semi-arid catchment : assessment of a catchment under rapid and uncontrolled urbanisation

    Författare :Benjamin Gossweiler; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The ongoing degradation of water quality and streamflow in rivers and streams worldwide is mainly due to human action through global land use change, particularly urbanisation. Population growth and economic development are major drivers of urbanisation, which causes environmental problems such as high water demand and solid waste and wastewater generation. LÄS MER

  4. 3. Biomass in a Sustainable Energy System

    Författare :Pål Börjesson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; economic valuation; environmental impact; carbon dioxide; Biomass; energy efficiency; Energiforskning; Energy research;

    Sammanfattning : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. LÄS MER

  5. 4. 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
