Hadamard well-posedness of the gravity water waves system

We consider in this article the system of (pure) gravity water waves in any dimension and in fluid domains with general bottoms. The unique solvability of the problem was established by Alazard-Burq-Zuily \cite{ABZ} at a low regularity level where the initial surface is $C^{3/2+\varepsilon}$ in term of Sobolev embeddings. Our result states that the solutions obtained above depend continuously on initial data in the strong topology where the solutions are constructed. This completes a well-posedness result in the sense of Hadamard.
