27. • Piping is especially likely in high banks backed by the valley side, a terrace, or some other high ground. In these locations the high head of water can cause large seepage pressures to occur. Evidence includes: Pronounced seep lines, especially along sand layers or lenses in the bank; pipe shaped cavities in the bank; notches in the …
Explanation: Straight drop or Overfall spillway is a low and simple vertical fall type structure. It is the simplest type of spillway and can be constructed on small bunds, thin arches, etc. The downstream face of the spillway may be kept vertical or slightly inclined.

The under-Sluices are the openings which are fully controlled by gates, provided in wall with their crest at a low level. They are located on the same side as the off-taking canal. Under sluices are …
Data from these sluices provided a basis to study the effects of length. Sluice Nos. I, VI and VII had the same feed and discharge end width. Their pinch angles were different. Therefore, sluices with larger pinch angle had a shorter length. The effect of pinch angle was examined comparing the performance of these sluices.
Sluice is a hydraulic control mechanism in reservoirs to release water into the main canal to meetirrigation requirement of crops. The hydraulics of the sluice and the sluice barrel is that of 'open channel

Due to this reason, they are also known as scouring sluices. While designing the capacity of under sluice, the following points should be considered. The capacity of the under sluices should be atleast double the canal discharging so that silt can be discharged to the downstream side easily. Under sluices shod; be capable of discharging winter ...

Scouring sluices are holes at the bottom of a or barrage that allow the sand to flow through them. Movable gates are used to cover these openings. When these gates are closed, silt builds up. When enough silt has built up, the gates are opened, and the silt flows through scouring sluices toward downstream. 4. Fish Ladder. Fig 5: Fish …
