The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Surface drainage systems remove excess precipitation runoff from the land surface before it can infiltrate and waterlog the crop root zone.
Step 2: Detailed Explanation:
The Parallel Field Ditch System is a standard surface drainage layout applied on flat, poorly drained, slowly permeable agricultural lands.
It consists of parallel, shallow, flat-sided open field ditches spaced \(20\text{ to } 100\text{ m}\) apart.
The field surface between ditches is smoothed and gently crowned/sloped toward the ditches, allowing excess rainfall runoff to drain rapidly into the ditches and discharge into lateral collector drains.
Step 3: Final Answer:
Thus, the parallel field ditch system is used for a Surface drainage system, corresponding to option (A).

- 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. - 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.
