    • 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 ...

    • Exogenous shore processes in water reservoirs of Belarus 

      Levkevich, Viktor E.; Kirvel, Ivan; Parfomuk, Sergey I. (De Gruyter Poland, 2020)
      The article presents the results of observations and research on the dynamics of exogenous erosion processes on the shores of lowland reservoirs in Belarus. Features and regularities of the dynamics of development of exogenous shores subject to abrasion-processing and an assessment of planned and ...

    • Lake water level variations in Belarus 

      Volchak, Aleksandr A.; Kirvel, Ivan (De Gruyter Poland, 2013)
      Lake level is one of the most important lake characteristics which allows the results of different effects to be identified and detected. In this work time series of the water levels of Belorussian lakes were analysed in order to detect pattern variations, to evaluate quantitatively the transformation ...

    • 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 ...

    • The changes of water resources in Belarus 

      Volchak, Alexander; Kirvel, Ivan; Parfomuk, Sergey (LIBRON, 2016)
      The total water resources in Belarus have not changed during last years. However, the redistri- bution of water resources for the basins of main rivers is specified. There was an increasing of runoff for the Pripyat and Western Dvina rivers, and a decreasing of runoff for the other rivers in ...

    • The present-day condition of water resources in Belarus 

      Volchek, Alexander A.; Kirvel, Ivan; Parfomuk, Sergey; Makhambetova, Roza (De Gruyter Poland, 2013)
      The optimal number of hydrological monitoring stations for the annual values, the maximum spring, the minimum summer-autumn and the minimum winter river runoff in Belarus is determined. The research on optimization of the hydrological network of Belarus led to a conclusion about the optimum number of ...

    • Wpływ zmian klimatu na reżim hydrologiczny małych rzek Polesia na przykładzie rzeki Jasielda 

      Kirvel, Ivan; Volchek, Aleksander; Parfomuk, Sergiey (Akademia Pomorska, 2016)
      Na podstawie metodyki hydrologiczno-klimatycznych obliczeń opracowano pro-gram, który daje możliwość modelowania bilansu wodnego małych rzek Polesia Białoruskiego. Zawiera on w sobie obszerne informacje o elementach bilansu wodnego badanych rzek i może uwzględniać główne charakterystyki fizycznogeograficzne ...
