The operating heads of the siphon-shaft spillways are limited by cavitational pressure due to
low siphonic pressure inside the spillway shaft. Therefore, these low pressures inside the …

Siphons are basic and powerful hydraulic instruments which can be used as dam spillway or
weir. In a siphon, atmospheric pressure pushes the water into the region of vacuum at the …

The Ortiglieto reservoir, in the Piedmont region of Northern Italy, was created barring the
Orba River with two dams: the main one, Bric Zerbino, having spilling facilities, the …

Issues such as the design or reauditing of dams due to the occurrence of extreme events
caused by climatic change are mandatory to address to ensure the safety of territories …

Siphon-shaft spillways are constituted by covering above a shaft spillway with a hood that
creates siphonic pressure. This study focused on the aeration the flow through the aerator …

In this paper, we investigated the performance of the Rambatan siphons in Indramayu
Regency, Indonesia, via physical modeling. The model was built in the laboratory with a …

Siphon-shaft spillways can discharge large amounts of water down to the crest level in a
narrow reservoir thanks to the siphonic pressures. However, cavitational pressures in the …

Spillways are the main hydraulic structures used to drain excess flow volume of dam
reservoirs. It is essential to study siphon overflows due to simple geometric structure …

In many projects for supplying water and energy, such as dams, the flow rate of water must
be controlled to achieve this goal. To that end, a special structure, called the dam's sSillway …
