    • Approaches to estimate the socio-economic risks caused by the river flood 

      Volchak, Aliaksandr Aliaksandrovich; Kostiuk, Dmitriy; Petrov, Dmitriy; Sheshko, Nikolay Nikolaevich (BrSTU, 2022)
      The issues of forecasting damage caused by flooding of anthropogenically transformed territories in a river floodplain of a plain type are considered based on the case of the floodplain of the Pripyat River. A method of spatial analysis of the level of the territory usage and the depth/duration of ...

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

      Volchak, Aliaksandr Aliaksandrovich; Parfomuk, Sergei Ivanovich; Sheshko, Nikolai Nikolaevich; Shpendik, Natalia Nikolaevna; Dashkevich, Denis Nikolaevich; 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 ...

    • Optimal strategy for water protection activity in regions 

      Volchak, Aliaksandr Aliaksandrovich; Shvedovsky, Petr Vladimirovich; Obrazcov, Leonid Vladimirovich; Sryvkina, Lyudmila Gennadievna; Kisel, Alena Ivanovna (БрГТУ, 2023)
      The methodology for constructing mathematical models to select the optimal strategy for water protection activity in the regions and for water consumers is considered. At the same time, the water environment is considered as a whole with all technical, environmental, economic and other problems ...

    • 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 ...
