    • Analysis of water resources in Belarus in view of climate changes 

      Kirvel, Ivan I.; Volchak, Alexander A.; Parfomuk, Siarhei I.; Kirvel, Pavel I.; Machambietova, Rosa (Pomeranian University, 2018)
      The surface water resources of Belarus for the period 1956-2015 were specified. The redistribution of water resources in the basins of the main rivers and administrative regions was investigated. The refined map of the Belarusian river runoff has been built. Runoff forecasts for 11 rivers in the Neman ...

    • Assessment of changes in the Viliya River runoff in the territory of Belarus 

      Volchak, Alexander A.; Parfomuk, Sergey I. (De Gruyter Poland, 2018)
      The research results of runoff changes in the River Viliya at 3 stations (Steshitsy Village, Vileyka Town and Mihalishki village) during the period 1946–2014 for the average annual, maximum, minimum summer-autumn and winter runoff are presented. It has been concluded that heterogeneity in the time ...

    • Evaluation of the Hydrochemical Regime of the Viliya River in the context of Environmental Problems of the Baltic Sea 

      Taratsenkava, Maya A.; Volchak, Alexander A.; Kirvel, Ivan I. (Pomeranian University in Slupsk, 2019)
      The article assesses the transformation of the hydrochemical regime of the river Viliya, belonging to the Baltic Sea basin. The dynamics of average annual values for the period from 1994 to 2017 according to 14 indicators of surface water quality is considered. The statistical parameters of ...

    • Modeling of the trajectory of the level fluctuations in Lake Naroch 

      Kirvel, Ivan I.; Volchak, Alexander A.; Parfomuk, Sergey I. (Bogucki Wydawnictwo Naukowe, 2016)
      As a result of the conducted investigations of the level fluctuations in Lake Naroch the initial data are divided into 3 components: a polynomial regression that makes it possible to find out an independent on time Law of trajectory, a periodic component of sinusoidal type and a residual sequence ...

    • 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 ...
