Validation of an unsteady flow numerical model for sediment transport induced by flushing operation in combined sewers

Abstract : An unsteady flow numerical model based on the solution of the 1-D De Saint Venant-Exner equations was developed and validated against the results of a field flushing experiment that was carried out in the year 2014 within a combined sewer trunk of the Paris sewer system. The comparison of numerical and experimental results showed that the model may reproduce in a proper way the erosional effects of the flush on the mobile bed of the sewer at the end of the experiment. Model results confirmed the potential erosive effect of the flush up to several hundreds meters downstream of the flushing device, with a significant reduction of the deposited sediments in the channel.
