The design of inward terrace cross section consists in deciding:
(A) The batter slope
(B) Dimension of shoulder bund
(C) Inward slope of terrace
(D) Alignment of drainage channel
(E) Terrace width
Choose the correct answer from the options given below:
Consider the following statements regarding irrigation channel crossings:
(A) Culverts are commonly used for channel crossings when the road fill is sufficiently high and the channel bed lies on the field surface on either side.
(B) The inverted siphon is more economical when a channel has to cross a wide depression or where road surface lie close to the field surface.
(C) Flumes are used to carry irrigation water across streams, canals, gullies, ravines or other natural depressions.
(D) It is often not necessary to carry irrigation channels across roads, hill side and natural depressions or drainage ways.
(E) When the siphon crosses a ridge, highway or bund it is called a flume.
Choose the correct answer from the options given below:
Given below are two statements:

Statement (I): Chute spillways carry the flow down the steep slopes through a lined channel rather than by dropping the water in a free overfall.

Statement (II): On steep slopes, chutes are more economical than series of drop structures to take the flow down the slope.

In light of the above statements, choose the most appropriate answer from the options given below.
Given below are two statements:

Statement (I): Water storage efficiency becomes important when water supplies are limited or when excessive time is required to secure adequate penetration of water into the soil.

Statement (II): Water application efficiency decreases as the amount of water applied during each irrigation increases.

In light of the above statements, choose the most appropriate answer from the options given below.
