Vertido anticipado en avenidas por medio de sifones regulables

Regulating siphons present important advantages when the discharge capacity of a dam needs to be augmented. In addition to the increase of discharge capacity other advantages include: the lack of effects on the operating conditions; no modification is needed to the normal maximum level or spill level; and it is possible to design a discharge rule for the siphon as appropriate.

Furthermore, it is possible for these siphons to begin discharging before the reservoir level reaches the threshold discharge level with the possibility of reducing the reservoir level before arrival of a flood event, thus improving the flood attenuation. In this paper the operation of a siphon to start working before the reservoir reaches the discharge threshold is described, as well as, how to limit the risk of operational error. Finally, an example of the effectiveness of these siphons is given.
