Siphon Spillway Slideshare. A siphon spillway is similar to a shaft spillway but instead is incorporated into the dam as shown in figure 6. When the reservoir water level rises above the normal level, the initial flow of water is similar to the flow.

Chute (open channel/trough) spillway 4. Of installing a siphon spillway is the reduced earthwork when compared to reinstalling a vertical riser system and ability to install without complete pond drainage.

Spillway

• shaft spillway becomes undesirable where a discharge more than the design capacity is to be passed. The size of the siphon is usually determined by the size of the lake and its watershed. Cascade spillway most of the spillways are of overflow types large capacities, higher hydraulic conformities, and adaptable to almost all types of dams. Of installing a siphon spillway is the reduced earthwork when compared to reinstalling a vertical riser system and ability to install without complete pond drainage.

The conduit system is in the shape of an inverted u of unequal legs with its inlet end at normal reservoir storage level. A straight drop spillway consists of low height weir wall having its downstream face roughly or perfectly vertical. Cascade spillway most of the spillways are of overflow types large capacities, higher hydraulic conformities, and adaptable to almost.

The presence of a siphon spillway weakens a dam at certain points, so the dam has to be reinforced at these weak points incurring extra cost.
