Research interests

  • similarities and differences between physical and statistical models, flood,
  • accuracy of mapping quantile of large return periods (the so-called "flood" quantiles) by procedures combining statistical models used in hydrology with different methods of estimation of their parameters,
  • robustness of the estimation methods of parameters and statistical flood quantiles to the shortcomings of the largest elements in the datasets
  • selection of the best hydrological model describing a given sample of measurement,
  • seasonal approach to modeling the maximum annual flow,
  • modeling the incidence of flooding in terms of the river regim instability,
