Modèles de simulation d'écoulement transitoire en réseau d'assainissement

Abstract : This thesis begins with a short historical review of water and town links for the defense of the interest of using mathematical models in urban hydrologie. Follows a synthetic description of flood routing mathematical models which gives a detailed analysis of the equations, their physical bases, their boundary conditions, numerical resolution techniques, and methods for adjusting the parameters Then, a series of results concerning hypothetical cases chosen to cover most of sewer network real conditions is produced. The methods for adjusting the parameters of simplified flood routing models have been checked. The numerical and hydraulical fields of applicability, depending on non-dimensional numbers, are pointed out referring to the results of a complete model solving full Saint-Venant equations. The possibility of taking into account a downstream boundary condition is tested with a diffusion model that was modified in order to be able to calculate a water line from downstream to upstream as if the flow was permanent. Finally, a study of the practical use of the models completes the thesis. This text is of greatest interest for all technical services of cities.
