The Design and Modelling of Air-Regulated Siphon Spillways.

Experimental assessment of the stage–discharge relationship of the Heyn siphons of Bric Zerbino dam

“…Experimental tests on a shaft spillway outfitted with a hood in order to function as a siphon can be found in Aguralioglu and Muftuoglu [1]. Ervine [5] identified four operating modes for siphon spillways: weir flow, sub-atmospheric weir flow, partial flow and backwater flow. More recently, pressure was measured inside hydraulic models of siphon spillways, comparing the results with those given by commercial CFD packages [6].…”
