  1. 16. Hydrology and water chemistry in a heterogeneous landscape : process-based modelling of coupled surface water and groundwater flow across contrasting boreal catchments

    Författare :Elin Jutebring Sterte; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Surface water and groundwater are connected, and the exchange between them is a vital part of a catchment’s hydrology. Along the flow paths through the catchment, biogeochemical processes can change the water’s chemical composition. LÄS MER

  3. 17. Sulfur isotopes used as a tracer of acidification reversal, dispersion of acid mine drainage and sulfur dynamics in small and large catchments

    Författare :Carl-Magnus Mörth; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Svavel;

    Sammanfattning : .... LÄS MER

  4. 18. Spatiotemporal streamflow variability in a boreal landscape : Importance of landscape composition for catchment hydrological functioning

    Författare :Reinert Huseby Karlsen; Jan Seibert; Kevin Bishop; Thomas Grabs; Sarah E. Godsey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; streamflow; catchment hydrology; boreal; water balance; spatiotemporal variability; landscape analysis; climate change; recession curve; Hydrology; Hydrologi;

    Sammanfattning : The understanding of how different parts of a landscape contribute to streamflow by storing and releasing water has long been a central issue in hydrology. Knowledge about what controls streamflow dynamics across landscapes can further our understanding of how catchments store and release water, facilitate predictions for ungauged catchments, and improve the management of water quality and resources.

  5. 19. Landscape hydrogeochemistry of Fe, Mn, S and trace elements (As, Co, Pb) in a boreal stream network

    Författare :Louise Björkvald; Carl-Magnus Mörth; Hjalmar Laudon; Christine Alewell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landscape hydrogeochemistry; boreal streams; spring flood; Fe; Mn; S; As; Co; Pb; sulphur isotopes; sulphate; organic S; DOC; spatial variability; temporal variability; wetlands; Earth sciences; Geovetenskap; geokemi; Geochemistry;

    Sammanfattning : The transport of elements by streams from headwater regions to the sea is influenced by landscape characteristics. This thesis focuses on the influence of landscape characteristics (e.g. LÄS MER

  7. 20. Intra-annual variability of natural organic matter in boreal streams : patterns and controls

    Författare :Mattias Winterdahl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Natural organic matter (NOM) is a key component in aquatic ecosystems. It influences for example acidity, mobility and toxicity of metals and organic pollutants, energy input to aquatic food webs, weathering, and water light conditions. There are also considerable costs associated with removing NOM in drinking water production. LÄS MER
