dc.description.abstract | This model is a improved version of a previously
published Two-Scales model 1111 and includes the
transport of particles in three spatial scales: small
(kilometres), medium (decades of km), and large
(hundreds of km). A 3-D dispersion model has been
developed to analyse and simulate the dispersion of
nuclear contaminants in marine ecosystems. This
model is characterized by presenting high spatial
resolution, by taking into account the possible
binding of a fraction of the Contaminants to the
suspended matter as well as its consequent
sedimentation, and especially by formulating the
diffusion processes using an original approach. The
horizontal resolution of the model is 20 km, while for
the vertical resolution a total of six layers are
considered. The Baltic Sea has heen elected as the
validation scenario of the model and the radionuclide
Cs-137 as the radiotracer to be analysed. This
scenario was the most contaminated ecosystem out of
the Sonet Union due to the Chernohyl accident
occurred at the end of April 1986, and the elected
radiotracer Cs-137 was the main long-lived
radioisotope emitted to the environment. A
computation time of approximately 9 hours by using
a Matlab code in a personal computer (AMD-1.4
GHz) was necessary. Different classical tools in
Oceanography as well as different numerical
methods (Monte Carlo, Finite differences) have been
properly implemented in the model. The approaches
adopted allow to save a lot of computational time [lo] | es |
