The management of sea resources is one of the major stakes of the 21st century. The work described in this thesis deals with the study of the migratory behaviour of eels glass in the estuary of the Adour river. The model, which consists of a degenerated convection-diffusion partial differential equation in 2 dimensions, takes into account the influence of dynamic tide cycles (Saint Venant's system of degenerated non linear equations) and the intensity of light in the water column. First, applying the theory of topological degrees, we have showed the existence of stationnary solutions within the hydrodynamic model. Then, by injecting these solutions into our migratory model, we have established the existence of these solutions by applying th...
