What is sought work presently is to contribute some existent recent information about the topic of the "Stable Channels with Mobile Channel" which are exposed with a focus of the problem and an outlined solution method. It should be mentioned that the present work doesn't represent all the conditions and variations in the characteristics of the behavior of the flow in the nature, because this it is quite complex, but yes it considers several of them, the engineer should also know that the application of the pattern presented for the design of these beds should be made taking in consideration the assumptions under which it was developed. The work contains a brief focus of the problem of the "Stable Channels with mobile Channel" a numeric model is also presented that considers the momentum diffusion an it allows the silt transport for the bed of channel, with the development of equations and ploteos developed by means of the calibration of the pattern in numerous runs(Vigilar and Diplas 1998), the results taken place by this model with those taken place by the most usual "cosine" method are also compared and for another that is that of the "treshold channel"(that we will call "cauce-limite"), design examples and the application are also included to two Peruvian rivers with the respective comparisons and analysis of the design parameters.
