| Zusammenfassung |
| The processes of transport, diffusion and transformation of surface oil in
seawater can be simulated using a Lagrangian model formalism coupled with
Eulerian circulation models. This paper describes the formalism and the
conceptual assumptions of a Lagrangian marine surface oil slick numerical model and
rewrites the constitutive equations in a modern mathematical framework. The
Lagrangian numerical representation of the oil slick requires three different
state variables: the slick, the particle and the structural state variables.
Transformation processes (evaporation, spreading, dispersion and coastal
adhesion) act on the slick state variables, while particle variables are
used to model the transport and diffusion processes. The slick and particle
variables are recombined together to compute the oil concentration in water,
a structural state variable. The mathematical and numerical formulation of
oil transport, diffusion and transformation processes described in this
paper, together with the many simplifying hypothesis and parameterizations,
form the basis of a new, open source Lagrangian surface oil spill model,
the so-called MEDSLIK-II, based on its precursor MEDSLIK (Lardner et al., 1998, 2006; Zodiatis et al., 2008a).
Part 2 of this paper describes the applications of
the model to oil spill simulations that allow the validation of the model
results and the study of the sensitivity of the simulated oil slick to
different model numerical parameterizations. |
