The hierarchy set of the models - box model, one-dimensional model, two-dimensional model and three-dimensional model are used to simulate local phenomena in the Prypiat river at the Chornobyl Nuclear Power Plant and radionuclide transport into the whole Dnieper river reservoirs system. Each model at its specific level of resolution simulates the flow dynamics, suspended sediment transport, radionuclide transport in dilute and on suspended sediments, radionuclides in bottom depositions. The modelling results were used to support the post-accident measures.
