Le transport solide en collecteur unitaire d'assainissement et sa modélisation

Abstract : The classical solid transport theory has been used to analyse the experimental results obtained from the N°13 combined sewer trunk of Marseille for more than two years. This study demonstrates that the sediment transport phenomena in a combined sewer trunk are nothing other than the classical ones. A numerical model has been established according to the analyses. Based on a permanent flow regime, this model considers not only the effets of the real channel geometries, non-uniform particles size, but also the co-existance of mineral and organical materials. Some particular sediment transport phenomena such as the pavement of bed have also been taken into account. It also shows that although the influence of the suspension particles is not necessarily considered, the simulation including the variations of particle density with each granular fraction may be improved.
