Apport de la teledetection a l'etude de la relation entre Phydrodynamisme de surface et les recifs coralliens

The factors governing reef dynamics are those that determine the lives of bio-constructive organisms. For the study area and near the surface, hydrodynamics constitute the major forces that mould reef structures. Basing ourselves on a multiscale approach, we shall attempt to sort out the various elements involved in this relation: (1) hydrodynamics: breakers and swells, (2) active and passive structures of coral reefs. The synthesis of these results, by elaborating on the way in which the reef ecosystem integrates and modifies hydrodynamic parameters, reaches far beyond the simple function of an inventory and constitutes a veritable tool for research and reflection on reef dynamics.
