    • Dynamics of aquatic resources change in Belarus in modern conditions 

      Volchek, Alexander Alexandrovich; Sidak, Svetlana Vasilievna; Parthomuk, Sergei Ivanovich (БрГТУ, 2021)
      The article addresses the main features of variability and dynamics of different river discharge in Belarus over 1948-2017. It has been found that for the 70-year period in question, the average annual discharge has slightly changed. The most significant changes are observed in the dynamics of the ...

    • Environmental problems caused by the extraction of non-metallic building materials from riverbeds 

      Волчек, Александр Александрович; Parfomuk, Sergei Ivanovich; Sheshko, Nikolai Nikolaevich; Shpendik, Natalia Nikolaevna; Дашкевич, Денис Николаевич; Sidak, Svetlana Vasilievna; Kukharevich, Mikhail Fedorovich; Rozumets, Ivan Nikolaevich (БрГТУ, 2023)
      Extraction of non-metallic building materials from rivers can lead to negative consequences, such as disruption of the structure of the river bed, change in the balance of sediment intake. It can also lead to the undermining of the fish food supply, destroy spawning grounds, and reduce the ability of ...

    • Regularities of variability in average monthly flow rates during the low-water period in the rivers of Belarus 

      Sidak, Svetlana Vasilievna; Volchak, Alexander Alexandrovich; Parfomuk, Sergey Ivanovich; Kofanov, Valery Anatolyevich (БрГТУ, 2023)
      The research is devoted to the study of long-term dynamics of fluctuations in average monthly flow rates during the summer-autumn and winter low-water periods in the rivers of Belarus. The assessment of extreme water flows of rare frequency in the summer-autumn period for the two time intervals ...

    • Spatial and temporal variability of the surface river runoff in Belarus 

      Volchak, Aliaksandr Aliaksandrovich; Parfomuk, Sergei Ivanovich; Sidak, Svetlana Vasilievna (BrSTU, 2022)
      An assessment of changes in the surface river runoff of Belarus in modern conditions is given. Significant negative trends were found for the series of the percentage of surface runoff in the total volume of annual runoff for the period 1948−2017. The greatest decrease in surface runoff is observed ...

    • Statistical assessment of the runoff time series homogeneity of the rivers in Belarus 

      Volchak, Aliaksandr Aliaksandrovich; Sidak, Svetlana Vasilievna; Parfomuk, Sergei Ivanovich (BrSTU, 2021)
      The article considers the need to evaluate the homogeneity of hydrological series using several statistical criteria, since the effectiveness of methods for testing homogeneity depends on the distribution of data. In addition to the officially recommended statistical parametric Student and Fisher ...

    • The climate change impact on the hydrological regime of the rivers in Belarus 

      Volchak, Aliaksandr Aliaksandrovich; Sidak, Svetlana Vasilievna; Parfomuk, Sergei Ivanovich; Sheshko, Nikolai Nikolaevich (БрГТУ, 2023)
      The article evaluates the changes in the parameters of the annual runoff, the maximum spring flood runoff and the main runoff-forming factors for the period 1988-2018 in relation to the period 1949-1987. The observed over the past decades climatic changes significantly change the situation of the ...
