Question

Group I contains three broad classes of irrigation supply canal outlets. Group II presents hydraulic performance attributes.

Group-I	Group-II
P. Non-modular outlet	1. Outlet discharge depends on the water levels in both the supply canal as well as the receiving water course.
Q. Semi-modular outlet	2. Outlet discharge is fixed and is independent of the water levels in both the supply canal as well as the receiving water course.
R. Modular outlet	3. Outlet discharge depends only on the water level in the supply canal.

The correct match of the items in Group I with the items in Group II is 

1. P-1; Q-2; R-3
2. P-3; Q-1; R-2
3. P-2; Q-3; R-1
4. P-1; Q-3; R-2

Answer 1

Correct Answer - Option 4 : P-1; Q-3; R-2

Non modular outlet: These are outlets through which the discharge depends upon the difference of head between the distributary and the water course.

Semi modular outlet: These are outlets through which the discharge is independent of the distributary so long as a minimum working head is available and depends upon distributary water surface level.

Modular outlet: These are outlets through which 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.
