    Sammanfattning : Data availability is extremely important for water management. Without data it would not be possible to know how much water is available or how often extreme events are likely to occur. The usually available hydro-meteorological data often have a limited representativeness and are affected by errors and uncertainties. LÄS MER

  3. 3. Vårflödesprognoser med utgångspunkt från snötaxeringar i Malmagenområdet

    Författare :Kurt-Åke Zakrisson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avrinning;

    Sammanfattning : The present paper deals with snow assessments as a basis for spring runoff forecasts.The investigation areas are glacier free drainage areas in the Swedish mountains at about 62°N, where the main interest was focused on an area of 100 km2 in which the snow cover during five subsequent winter seasons were assessed by various methods.

  4. 4. 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.

    Sammanfattning : Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. LÄS MER
