If the free surface does not move (no waves), a symmetry boundary condition is enough. If it does move, you need to add ALE deformation, but you have de define mesh motion correctly in this case.
If I apply the symmetry condition I'll get an interaction water / air?, I get drops of air in the bassin?
if yes, then this condition is enough for me ! for ALE, I do not know how to add it,

No, if you apply symmetry, you get no interaction between water and air.
To get drops of water in the air domain would require another approach than continuum mechanics implemented in Code_Saturne, or at the minimum a multiphase approach with an appropriate model.
I think I have used the polyphasic approach (Euler-Lagrange) but I can't find any examples of this subject conducted by Code_Saturne.
What I have now is a coupling between two areas ( rotating and fixed areas) (Fig. above),but I don't know that they are subroutines to add to my SRC.1 to use the polyphasic approach!.
Please if you have an idea of how to proceed, thank you for the past for me, and if there are examples in polyphasic on code saturne are welcome
The only "polyphasic approaches" in Code_Saturne are the ones for combustion, which use specific models, so they won't help here (and in addition, I do not have examples that I could explain for those).

For the sake of completeness, let us mention the particle-tracking (Lagrangian) module of Code_Saturne to deal with polydisperse particulate turbulent flows
(of course, absolutely irrelevant when it comes to free-surface flows)
