Prediction of radionuclide migration in the Pripyat river and Dnieper reservoirs and decision support of water protection measures on the basis of mathematical modelling
[en]Since May 1986 in Kiev in the Institute of Mathematical Machines and System Problems, Cybernetics Center of the National Academy of Sciences of Ukraine has been started the development of the computerised system for processing of Dniper basin radiological monitoring data and modelling of radionuclide dispersion in rivers and reservoirs. For this work it was established the Interdisciplinary Working Group that joints the specialists from the State Committee of Water Resources, State Committee of Hydrometeorology, National Academy of Sciences and other Ukrainian institutions. The objectives of the computerized system development were formulated by the State Emergency Commission and later by the Ukrainian Minchernobyl as follows: reliable evaluation of the surface water contamination at Pripyat River and Dnieper River on the basis of monitoring data from the different institutions; seasonal and long-term prediction of the surface water radioactive contamination; decision support for the aquatic post-accidental countermeasures, directed to diminish the radionuclides fluxes from the Chernobyl area through the Pripyat River and Dnieper Reservoirs; decision support for the countermeasures directed on changes in the water assumption
