QUESTION: 1

Solution:
QUESTION: 2

### Canal modules help in

Solution:

A canal outlet or a module is a small structure built at the head of the watercourse so as to connect it with a minor or a distributary channel.

QUESTION: 3

### Canal outlets are also called

Solution:
QUESTION: 4

A good irrigation module is the one, which

Solution:

A good irrigation module should fit well to the decided principles of water distribution. It should be simple and cheap. It should draw its fair share of silt.

QUESTION: 5

The rate of change of discharge through an irrigation outlet becomes equal to the rate of change of water depth in the channel, when its.

Solution:

Sensitivity is defined as the ratio of the rate of change of discharge through the outlet to the rate of change of water level of the distributary, referred to the normal depth of the channel.

QUESTION: 6

A fully modular canal outlet has its

Solution:

Rigid modules or modular outlets are those through which the discharge is constant and fixed within limits irrespective of the fluctuations of the water levels of either the distributary or of the water course or of both .
∴  sensitivity = 0, and flexibility = 0.

QUESTION: 7

An irrigation outlet is said to be proportional, when its

Solution:

The outlet is said to be proportional when the rate of change of outlet discharge equals the rate of change of channel discharge.
∴ outlet is, 'proportional' when flexibility’ equals unity.

QUESTION: 8

A free pipe outlet is a

Solution:

Pipe outlet discharging freely into the atmosphere is the simplest and the oldest type of a flexible outlet. The discharge through such an outlet will depend only upon the water level of the distributary, and will be independent of the water level of the watercourse.

QUESTION: 9

For a specified weir foundation geometry and applied head, the pressure distribution on the base of the impervious floor of a weir is

Solution:
QUESTION: 10

When seepage takes place below a horizontal floor without any sheet piles, the streamlines are
