Test: Canal Regulators- 2 - Question 1

When seepage flow takes place below a flat floor without any sheet piles, the potential fx below the floor at 1/4 floor length from the upstream end is

Test: Canal Regulators- 2 - Question 2

The Khosla’s formula for the correction C, to be applied to the seepage potential below a weir , floor, to account for the mutual interference of a pile of depth D on an adjacent pile of depth d, separated by a distance b1 in a total floor length of b is

Test: Canal Regulators- 2 - Question 3

A canal fall is a control structure

Detailed Solution: Question 3

When the available natural ground slope is steeper than the designed bed slope of the channel, the difference is adjusted by constructing canal falls or drops. The location of fall depends upon the topography, command area and the possibility of combining it with a bridge, regulator, or some other masonry work, since such combinations often result in economy and better regulation.

Test: Canal Regulators- 2 - Question 4

A submerged pipe outlet is an example of

Detailed Solution: Question 4

Non-modular outlets are those through which the discharge depends upon the difference of head between the distributary and the water course. The discharge through such a module, therefore, varies widely with either a change in the water level of the distributary or that of the water course. The common examples of this type of outlets are (i) open sluice and (ii) drowned pipe outlet.

Test: Canal Regulators- 2 - Question 5

An outlet in which the discharge depends upon the difference in level between the water levels in the distributing channel and the water course is called

Test: Canal Regulators- 2 - Question 6

The possible functions of a distributary head regulator are
1. to regulate the supply entering the distributary from parent channel
2. to maintain a constant water depth in the distributary
3. to control the silt charge entering into the distributary
4. to ensure safe passage of fish into the distributary

Which of these statements are correct?

Test: Canal Regulators- 2 - Question 7

The outlet discharge factor is

Detailed Solution: Question 7

Duty at the head of water course called outlet discharge factor.

Test: Canal Regulators- 2 - Question 8

The capacity factor of a canal is

Detailed Solution: Question 8

Capacity factor is the ratio of mean supply discharge to the full supply discharge.
