Syphon Aqueduct: In a syphon aqueduct, canal water is carrier above the drainage but the high flood level (HFL) of drainage is above the canal trough. The drainage water flows under syphonic action and there is no presence of atmospheric pressure in the natural drain.

IS 7784-2-5 (2000): Code of Practice for Design of Cross Drainage Works, Part 2: Specific Requirements, Section 5: Syphon Aqueducts [WRD 13: Canals and Cross Drainage Works]

If two canals cross each other and one of the canals is siphoned under the other, then the hydraulic structure at the crossing is called “canal siphon”. In the case of the siphon, the F.S.L. of the canal is much above the bed level of the drainage trough, so …

All these different types of cross drainage works are described below in details. 14.2.1. Aqueduct and Syphon Aqueduct. In these works, the canal is taken over the natural drain, such that the drainage water runs below the canal (see Fig. 14.2) either freely or under syphoning pressure. When the HFL of the drain is sufficiently below the DRAIN

1995年2月1日 · An aqueduct is a cross drainage work in which the carrier channel is carried over the drainage channel and the bottom of the trough or the covering over the drainage openings is above the high flood level

2024年8月26日 · Syphon Aqueduct. A syphon aqueduct is a type of cross drainage work. The irrigation canal flows over a drainage channel through an enclosed conduit. This design uses siphonic action to maintain water flow, even across steep gradients. In the syphon aqueduct, the canal bed level is below the full supply level.

2017年3月27日 · A siphon aqueduct is a type of cross drainage work that combines the features of both an aqueduct and a siphon. It is designed to carry water over an obstacle, such as a valley or a depression, using the principle of a siphon. In a siphon aqueduct, a pipeline or conduit is constructed with one end higher than the other, creating a slope or ...

When the canal has small discharge compared to the drain, it is taken below the latter by constructing the syphon against a syphon aqueduct, which is constructed when the drain with smaller discharge is taken below a large canal.

2023年6月14日 · Aqueducts are similar to bridges in that they carry canal water in a trough, below which drainage water flows under the influence of gravity and air pressure. Fig 1: Siphon Aqueduct. In a siphon aqueduct, the canal trough is above the drainage, while the drainage has a high flood level (HFL) above the canal.

In this research we are considering an aqueduct which is located in Puligadda and it is designed as a syphon aqueduct for reducing the damages during floods and to avoid flood intensity across the delta areas which provide irrigation water to fertile soil in Diviseema.
