1. 1. 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.

3. 2. 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

4. 3. Chlorine Transport in a Small Catchment

   Författare :Teresia Svensson; Gunilla Öberg; Katarina Abrahamsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catchment; chloride; chlorine; chloroform; organic chlorine; runoff water; soil; VOCls; avrinningsområde; avrinningsvatten; flyktiga klorerade föreningar klor; klorid; kloroform; organiskt klor; mark; Water in nature and society; Vatten i natur och samhälle;

   Sammanfattning : De senaste decenniernas forskning har påvisat att en omfattande bildning och nedbrytning av klororganiska föreningar sker i mark. Bildning av sådana föreningar sker genom att klorid binds in i organiskt material. LÄS MER

5. 4. The Integrated Distributed Hydrological Model, ECOFLOW- a Tool for Catchment Management

   Författare :Nikolay Sokrut; Roger Thunvik; Tuomo Karvonen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogeology; Multiple-scale hydrological modelling; Bayesian algorithm; Parameter estimation; Groundwater management; Statistical analysis; Hydrogeologi; Hydrology; Hydrologi;

   Sammanfattning : In order to find effective measures that meet the requirements for proper groundwater quality and quantity management, there is a need to develop a Decision Support System (DSS) and a suitable modelling tool. Central components of a DSS for groundwater management are thought to be models for surface- and groundwater flow and solute transport. LÄS MER

7. 5. 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
