  3. 2. Lake Evaporation Estimation by Isotope, Energy Balance and Bulk Aerodynamic Methods

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskap

    Författare :Christian Jaedicke; [1997]
    Nyckelord :;

    Sammanfattning : Lake evaporation from a shallow lake in central Sweden has been estimated using three independent methods from measurements during summer 1995.
