Abstract: The aim of this article is to study a model of two superposed layers of fluid governed by the shallow water equations in space dimension one. Under some suitable hypotheses the governing equations are hyperbolic. We introduce suitable boundary conditions and establish a result of existence and uniqueness of smooth solutions for a limited time for this model.

Keywords:  Shallow water equations, two layers fluid, transparent boundary conditions, strictly dissipative boundary conditions.
