Última TRANSMER, un modèle hydrodynamique rapide et précis pour la simulation à moyen et long terme des transferts de radionucléides en Manche et dans le sud de la Mer du Nord ArchiMer Bailly Du Bois, Pascal; Dumas, Franck. TRANSMER hydrodynamic model simulates dispersion of dissolved substances in seawater at the scale of the English Channel and the south of the North Sea with a mesh size of one kilometre and a time step of 30 minutes. It has been qualitatively and quantitatively validated by 1400 measurement of 125Sb in seawater. This model evaluates the medium- and long-term consequences of releases of soluble pollutants in the marine ecosystem under normal or accidental conditions, at a very low computation cost (it takes less than one hour to simulate one year).

Ano: 2004 URL: http://archimer.ifremer.fr/doc/2004/acte-563.pdf Fast hydrodynamic model for medium- and long-term dispersion in seawater in the English Channel and southern North Sea, qualitative and quantitative validation by radionuclide tracers ArchiMer Bailly Du Bois, Pascal; Dumas, Franck. The database for medium- and long-term model validation using Sb-125 released by the La Hague reprocessing plant includes 1400 measurements performed between 1987 and 1994 in the English Channel and the North Sea and data for each release since 1982. Antimony-125 has a conservative behaviour in water masses over a period of several years. These data can be used qualitatively and quantitatively to compare the measured concentrations with the calculated ones and quantities of tracers. Tritium measurements are also available for model calibration. A two-dimensional hydrodynamic model has been developed to allow repetitive long-term simulations. This model uses a database of residual tidal currents calculated using the Lagrangian barycentric method [Salomon,...
