An asymptotic framework is also presented in order to elaborate simplified 1D two (or 3) equations models when the topography of the 2D models presents characteristics of 1 dimensionnal channel with general shape of cross sections. In the special case of Shallow water equations of hydraulic the new models are compared to the classical one used in standart hydraulic
