    Sammanfattning : Models of climate change predict that temperature will increase during the 21th century and the largest warming will take place at highnorthern latitudes. In addition to warming, predictions for northern Europe include increased annual precipitation and a higher proportion of the precipitation during winter falling as rain instead of snow. LÄS MER

  3. 3. Environmental Modelling of Hydrological Systems

    Detta är en avhandling från Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Författare :Arabinda Ghosh Bobba; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; teknisk geografi; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; uncertainty analysis; data analysis; lake Ontario; contamination; lake sediments; hydrogeochemistry; acidification; non-point pollution; climate change;

    Sammanfattning : Global problems such as atmospheric change, acid rain, and water pollution in surface and subsurface environments dominate discussions of world environmental problems. In this thesis the roles of hydrologic processes and hydrogeochemical processes are investigated through development, modification, and application of models for addressing point and non-point source contamination of water.

  4. 4. GIS-hydrological modelling in arid lands : a geographical synthesis of surface waters for the African Red Sea region in the Sudan

    Detta är en avhandling från Lund University Press

    Författare :Badr-Eldin Taha Osman; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teknisk geografi; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; runoff.; infiltration; evaporation; rainfall; deterministic and stochastic explanations; weighting methods; hydrological modelling; spatial modelling; GIS; geographical hydrology; the Sudanese Red Sea region; arid lands; water resources;

    Sammanfattning : The magnitude and availability of surface waters in the arid/semi-arid Sudanese Red Sea region has been examined. In conjunction with the research objective, opinions and methodologies applied by previous researchers have been assessed. The study applied a geographical hydrological synthesis within a GIS framework. LÄS MER

  5. 5. Climate change and urban drainage future precipitation and hydraulic impact

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Mats Olofsson; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Increasing global mean temperature influences the hydrologic cycle. In the 21st century, hydrologic change featuring more heavy precipitation events is very likely according to the UN Intergovernmental Panel on Climate Change, IPCC. This change will have a great impact on urban environments and infrastructures. LÄS MER
