4. The uplift pressure on the roof of an inverted syphon, is maximum when
5. Effective precipitation for a crop may be defined as
6. While deciding the alignment of a proposed canal taking off from a river at B, three alignments of approximately equal lengths are available. These cross a drainages at C1, C2 and C3 where drainage bed levels C1 > C2 > C3, you will provide at site C3

17. The water face of the guide banks, is protected by
18. Lane's weighted creep theory assumes
19. The ratio of the discharge over a trapezoidal crest to a rectangular crest of Sarda falls of identical parameters, is
20. Garnett's diagrams are used for graphical solution of design equations of a canal by
