Fluming of the canal section

Fluming is a method used in canal construction to create a waterway with a controlled flow. It involves constructing a flume or a channel within the canal section to facilitate the flow of water. The flume is typically built using reinforced concrete or other suitable materials to ensure its durability and stability. Fluming offers several advantages in terms of economy, construction, and maintenance of the canal. However, it is important to understand the correct statements about the fluming of the canal section.

Incorrect statement: Fluming of the canal expands the waterway of the canal (Option A)

The correct answer is option A, which states that fluming of the canal expands the waterway of the canal. This statement is not correct. Fluming of the canal does not expand the waterway, but rather it creates a narrower channel within the canal section to control the flow of water. The flume acts as a guide for the water, ensuring that it flows smoothly and efficiently through the canal. By confining the water within a narrower channel, fluming reduces the width of the aqueduct, providing a controlled path for the water to follow.

Correct statements:

1. Fluming leads to economy in construction (Option B)

Fluming offers significant cost savings in canal construction. By creating a narrower waterway, less material is required for excavation and embankment. This reduces the overall construction cost of the canal. Additionally, the use of reinforced concrete or other durable materials for constructing the flume ensures its longevity, reducing the need for frequent repairs and maintenance.

2. Fluming reduces the width of the aqueduct (Option C)

Fluming effectively reduces the width of the aqueduct. By confining the water within a narrower channel, the need for a wider aqueduct is eliminated. This reduces the material and construction costs associated with building a wider aqueduct. Moreover, a narrower aqueduct is easier to maintain and provides better control over the flow of water.

3. Fluming is not done when the canal section is in earthen banks (Option D)

Fluming is typically not done when the canal section is in earthen banks. The process of fluming requires the construction of a reinforced concrete channel or flume, which is not feasible on earthen banks. Instead, fluming is more commonly used in canal sections with stable and durable banks, such as those made of concrete or masonry. In cases where the canal section is in earthen banks, alternative methods of controlling the flow of water, such as lining the banks with impermeable materials, may be employed.

In conclusion, fluming of the canal section does not expand the waterway of the canal. Instead, it creates a narrower channel within the canal section. Fluming leads to economy in construction, reduces the width of the aqueduct, and is not done when the canal section is in earthen banks.
