When the water level on the downstream side of a weir is above the top surface of a weir, it is known as submerged or drowned weir, as shown in the figure. The total discharge over such a weir is found out by splitting up the height of the water, above the sill of the weir, into two portions.

The correct answer is option 'C': Above crest level.
A submerged weir is a type of weir where the water level on the downstream side of the weir is above the crest level of the weir. This means that the water level is higher on the downstream side compared to the upstream side.
Explanation:
1. Definition of a weir:
- A weir is a barrier across a river or stream that is used to control the flow of water.
- It is typically made of concrete or masonry and is designed to have a specific shape to regulate the water flow.
2. Crest level:
- The crest level of a weir refers to the top edge or crest of the weir structure.
- It is the highest point of the weir and determines the maximum water level that can be maintained upstream.
3. Submerged weir:
- In a submerged weir, the water level on the downstream side is higher than the crest level of the weir.
- This occurs when the water flow rate is high and the water level rises above the crest level of the weir.
4. Reasons for water level above crest level:
- The water level on the downstream side of the submerged weir is higher due to the hydraulic jump phenomenon.
- A hydraulic jump occurs when there is a sudden change in water flow velocity, resulting in a turbulent flow.
- This turbulent flow causes the water level to rise above the crest level of the weir.
5. Effects of a submerged weir:
- A submerged weir can help dissipate energy and reduce the velocity of the water flow.
- It can prevent erosion and damage downstream by controlling the flow rate.
- The higher water level on the downstream side also helps to maintain a more constant flow rate upstream of the weir.
In conclusion, a submerged weir is a type of weir where the water level on the downstream side is above the crest level of the weir. This occurs due to the hydraulic jump phenomenon and helps to regulate the flow rate and prevent erosion downstream.
