Abstract
In this work we present a classical evolution equation for the movement of oil
slicks in marine water in its second phase (Fay, 1969), and, setting it in its
variational formulation, discretize it with a view towards the use of the Finite
Element Method (using first degree approximations for oil concentration). For
simulating marine currents special upwinding techniques are adopted so as to
eliminate main oscillations caused by numerical options. These currents are
given by the solution of Stokes' equation using second order finite elements, and
boundary conditions are obtained from data furnished by the Brazilian National
Hydrographic Directory. Resulting currents were then used for a qual
