Vortex dropshafts are used in urban drainage systems to connect two sewers located at considerably different elevations. After their introduction in 1947 as overflow structure in dam engineering, these were studied with particular reference to subcritical approach flow. Vortex shafts for supercritical approach flow can also be used; in this case the geometry of intake structure is rather complex, thus inducing relatively high construction costs. The basic design criteria are illustrated along with some recent findings based on experimental studies.

Abstract
Vortex dropshafts are used in urban drainage systems to connect two sewers located at considerably different elevations. After their introduction in 1947 as overflow structure in dam engineering, these were studied with particular reference to subcritical approach flow. Vortex shafts for supercritical approach flow can also be used; in this case the geometry of intake structure is rather complex, thus inducing relatively high construction costs. The basic design criteria are illustrated along with some recent findings based on experimental studies.File in questo prodotto:
