摘要: Results of numerical modeling sediment flushing in a combined sewer reach are herein presented. Simulations were performed by using model based on the solution De SaintVenant–Exner equations TVD MacCormack scheme. The model, previously validated means data derived from laboratory experiments, was applied to Lacassagne trunk Lyon, France. A Hydrass gate put into operation at this site 2003 remove sediments accumulated during 3 years. 5-month long experimental campaign carried out measure profile evolution operations. Four transport formulas used for simulations and compared. proved be able reproduce correctly global profiles as function number
