| Abstract |
We report here investigations of the energy-and-rnass exchange processes that determine ventilation of the Black Sea anoxic waters and propagation of pollution in the bottom boundary layer of the Black Sea. Special emphasis has been put on possible propagation of Chernobyl radioactive substances via physical mechanisms such as the global circulation, near-bottom gravity and turbidity currents, internal waves, large-scale eddies and chemical processes in near-bottorn layer. One of the key problems in this study has been the modeling of mechanisms of the backward transport of radionuclides during bottom storms from deep water regions toward the beaches and surf zone of the Black Sea. We have investigated the near-bottom density and turbidity current diagnostics and calculation methods for the forecast of these flows on radionuclide transport. Such currents may be catastrophically powerful and may contaminant surrounding waters over tens of meters above the bottom level. The elaboration of current structure diagnostic methods based on the results of spectra analysis of suspended particle size and of current parameter distributions measurements have been performed both in depth and in time. This study was supported by the EC Commission, contract No.ICI5-CT96-0113, and the IAEA, contract No.7332 RB. |
