  2. 1. Bacteria that escape predation : waterborne pathogens and their relatives

    Author : Karolina I. A. Eriksson; Agneta Andersson; Johanna Thelaus; Jon Ahlinder; David Sundell; Klaus Jürgens; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial pathogens; protozoa; predation resistance; aquatic microbiology; climate change; opportunists; humification; iron; environmental science; miljövetenskap; mikrobiologi; Microbiology;

    Abstract : The hidden presence of opportunistic bacterial pathogens in the environment evokes concerns about emerging diseases, especially in the light of climate change. The co-evolution of bacteria and their predators (protozoa) has led to bacterial defence strategies of which some contribute to the ability of bacteria to cause disease. READ MORE

  4. 2. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

    Author : Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Linking water and permafrost dynamics

    Author : Ylva Sjöberg; Steve Lyon; Andrew Frampton; Britta Sannel; Georgia Destouni; Michelle Walvoord; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; hydrology; arctic; modeling; streamflow; geophysical measurements; ground thermal dynamics; groundwater; Physical Geography; naturgeografi;

    Abstract : The extent and dynamics of permafrost are tightly linked to the distribution and movement of water in arctic landscapes. As the Arctic warms more rapidly than the global average, profound changes are expected in both permafrost and hydrology; however, much is still not known about the interactions between these two systems.

  6. 4. Hydraulic- hydromorphologic analysis as an aid for improving peak flow predictions

    Author : Anna Åkesson; Anders Wörman; Göran Lindström; Rolf Larsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrological modelling; peak flow predictions; distributed routing; parameterisation; stage-dependency; Hydrology; Hydrologi;

    Abstract : Conventional hydrological compartmental models have been shown to exhibit a high degree of uncertainty for predictions of peak flows, such as the design floods for design of hydropower infrastructure. One reason for these uncertainties is that conventional models are parameterised using statistical methods based on how catchments have responded in the past. READ MORE

  7. 5. Pit lake water quality and hydrology : Insights from case studies and modelling of pit lakes in northern Sweden

    Author : Oscar Paulsson; Anders Widerlund; Lars Lövgren; Adam P. Jarvis; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

    Abstract : As extraction techniques are improving an increased number of low grade deposits can be economically mined. However, this also means that the number of open pit mines will increase and as a result the number of pit lakes as well. READ MORE
