Finally, some conclusions are made in Section 4 2 Materials and Methods 2.1 Eulerian Mathematical Model Mathematical modelling of the transport and diffusion of an oil spill in the sea is of high interest to remediate the environmental impact (e.g., [ 24 , 25 , 26 ]). We have developed an Eulerian model for the case where the density of the pollutant is smaller than that of one of the sea water (so that it remains at the surface) and assuming that the layer-thickness of the pollutant h , is

of fluid dynamics [ 8 , 24 ] or the Koterweg de Vries equations (KdV) which model waves on shallow water surfaces [ 17 , 25 ]. In the present paper we are going to focus our attention in Koterweg de Vries equations. The KdV equation u t + λ u u x + μ u x x x = 0 $$ \begin{equation} u_t+\lambda u u_x + \mu u_{xxx}=0 \end{equation} $$ (1) was arised to model shallow water waves with weak nonlinearities and it is probably the most studied nonlinear evolution equation due to its wide applicability. The KdV equation ( 1 ) was generalized to a standard fifth order

1 Introduction This paper is mainly devoted to studying the regularity properties of global attractors for multivalued semiflows generated by strong solutions of reaction-diffusion equations. The existence and properties of global attractors for dynamical systems generated by reaction-diffusion equations have been studied by many authors over the last thirty years. For equations generating a single-valued semigroup such results are well known since the 80s (see e.g. [ 5 ], [ 6 ], [ 7 ], [ 8 ], [ 24 ], [ 34 ]). Moreover, deep results concerning the structure of

As far as the shape derivative of P uw (Ω) is concerned, the exact same proof as that of Theorem 2 can be worked out, taking advantage of the definition ( 23 ) of g h , and the conclusions of this Theorem extend verbatim to

In view of Eq. (17) , the system in Eqs. ( 15 - 16 ) is transformed to the form α 2 G ‴ + 1 2
