1. 6. Water quality modeling based on landscape analysis: importance of riparian hydrology

   Författare :Thomas Grabs; Jan Seibert; Kevin Bishop; Hjalmar Laudon; Brian McGlynn; Georgia Destouni; Irena Creed; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water quality model; terrain analysis; geographical information system GIS; riparian zone; total organic carbon TOC; boreal catchments; Hydrology; Hydrologi; geografi med naturgeografisk inriktning; Physical Geography;

   Sammanfattning : Several studies in high-latitude catchments have demonstrated the importance of near-stream riparian zones as hydrogeochemical hotspots with a substantial influence on stream chemistry. An adequate representation of the spatial variability of riparian-zone processes and characteristics is the key for modeling spatio-temporal variations of stream-water quality. LÄS MER

3. 7. Making water information relevant on local to global scale – the role of Information Systems for Integrated Water Management

   Författare :Fredrik Hannerz; Georgia Destouni; Dennis Lettenmaier; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integrated water management; hydrology; environmental information systems; environmental monitoring; land cover; GIS; Sweden; Baltic Sea; European Union; global water; global change; Water Framework Directive; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Sammanfattning : Relevant information is essential for finding solutions in Integrated Water Management (IWM). Complex water systems and a need for increasing integration of sectors, actors and scales in IWM require new methods for developing and managing such information. LÄS MER

4. 8. Waterborne Carbon in Northern Streams : Controls on dissolved carbon transport across sub-arctic Scandinavia

   Författare :Elin Jantze; Steve W. Lyon; Georgia Destouni; Helen Dahlke; Pirkko Kortelainen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissolved carbon; DOC; DIC; TOC; sub-arctic; hydrology; Abisko; Physical Geography; naturgeografi;

   Sammanfattning : Waterborne carbon (C) forms an active and significant part of the global C cycle, which is important in theArctic where greater temperature increases and variability are anticipated relative to the rest of the globe withpotential implications for the C cycle. Understanding and quantification of the current processes governing themovement of C by connecting terrestrial and marine systems is necessary to better estimate future changes ofwaterborne C.

5. 9. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

   Författare :Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

   Sammanfattning : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

7. 10. The influence of climate and permafrost on catchment hydrology

   Författare :Emma Johansson; Georgia Destouni; Sean Carey; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Periglacial; Greenland; Forsmark; Talik; Permafrost Hydrology; Hydrology; hydrologi;

   Sammanfattning : The cycling of water in the landscape is influenced by climate change on different time scales and in different directions regarding warming or cooling trends. Along with a changing climate, also the landscape and subsurface conditions, such as permafrost extent, may change in a long-term perspective. LÄS MER
