title: Hydraulics of a sewer flushing gate.
abstract: This paper presents field experiments carried out in a 1.8 m height egg-shaped sewer in Lyon, France in order to contribute to the knowledge and the simulation of Hydrass flushing gates. The main results are: i) definition of an empirical relationship giving the flow discharged by the gate as a function of the upstream water level and its use in modelling the gate behaviour, and ii) observation of the flush propagation along the sewer and evaluation of the potential cleansing efficiency.
