Hydraulics of a sewer flushing gate
Water Science and Technology, 2003 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 ...

Hydraulic Approach to Flush Systems for Dairy Manure Removal
Sixth International Dairy Housing Conference Proceeding, 16-18 June 2007, (Minneapolis, Minnesota) (Electronic Only), 2007 The following note characterizes the hydraulic behavior when removing manure from alleys through the flush system in dairy freestall barns. The flush system guarantees the moving, the conveyance and the removal of manure from the alleys flooring, depending on the main manure flux characteristics.
