    • Analysis of Lake Water Levels Fluctuations in Poland and Belarus 

      Choiński, Adam; Volchak, Aleksander; Kirvel, Ivan; Parfomuk, Sergey; Sidak, Svetlana; Kirvel, Pavel (SGGW Water Center, 2020)
      On the basis of the mean volume of annual water levels for 25 lakes (9 Belarusian and 16 Polish) in the period of 55 years (1956-2010) the spectral time analysis of water levels fluctuations has been executed. The spectral time analysis included two parts: analysis based on calculating the variance ...

    • Effect of Air Temperature Increase on Changes in Thermal Regime of the Oder and Neman Rivers Flowing into the Baltic Sea 

      Choiński, Adam; Ptak, Mariusz; Volchak, Alexander; Kirvel, Ivan; Valiuškevičius, Gintaras; Parfomuk, Sergey; Kirvel, Pavel; Sidak, Svetlana (MDPI, 2021)
      The paper presents long-term changes in water temperature in two rivers, Oder and Neman, with catchments showing different climatic conditions (with dominance of marine climate in the case of the Oder and continental climate in the case of the Neman River). A statistically significant increase in mean ...

    • Spectral–time analysis of cycle fluctuations in lake water levels in Belarus and Poland 

      Volchak, Alexander A.; Kirvel, Ivan; Choiński, Adam; Parfomuk, Sergey I.; Kirvel, Pavel; Sidak, S. (De Gruyter Poland, 2020)
      On the basis of the mean volume of annual water levels of 25 lakes (9 Belarusian and 16 Polish) over a period of 55 years (1956-2010) spectral time analysis of water fluctuations has been executed. The choice of the lakes was based on two factors, i.e. the continuous period of observation and ...
