In this talk we will explain how it is possible to enhance the existence (beyond the hyperbolic time-scale) on different systems derived from the water wave equations. Our goal is to show how these methods are perturbed when the dispersion is weak and to discuss which existence time we want to attain. We will also study the rigid lid limit problem on these systems.
