Multiple Inflow Branches at Supercritical-Type Vortex Drop Shaft

Michael Pfister, Jean-Marc Ribi, Corrado Gisonni, Gaetano Crispino, Thierry Fuchsmann

Vortex drop shafts serve to overcome important elevation differences in drainage systems. If well designed, they are performant in terms of energy dissipation and safety. However, the standard design requires well-defined approach flow conditions to ensure ...

Junction chamber at vortex drop shaft: case study of Cossonay

Michael Pfister, Corrado Gisonni, Gaetano Crispino, David Dorthe, Thierry Fuchsmann

The drainage network of the city of Cossonay (Switzerland) is currently being adapted for future needs. In particular, it is required to drain increased storm discharges due to a population augmentation and to provide an adequate concept to overcome unfavo ...

Head losses in junction manholes for free surface flows in circular conduits

Michael Pfister, Corrado Gisonni

Former studies on combining flows resulted in an efficient layout of sewer junctions operated under supercritical approach flow conditions. Straight extensions allowed a reduction in the shock wave heights generated by the merging flows, so that the global ...
