In this talk I will present some recent results concerning the existence and the stability of quasi-periodic solutions for the 2D-Euler equation of an irrotational and incompressible fluid under the action of the gravity. After an overview on the KAM theory for PDEs, I will discuss the tools needed in order to prove KAM theory for PDEs with quasi-linear and fully-nonlinear nonlinearities.                                                                                                 The proof is obtained by combining perturbation theory (which comes from the world of Dynamical systems) and Pseudo differential calculus (which comes the world of microlocal analysis).
