[3 marks]Define duty and delta. Derive a relationship between them.
[4 marks]After how many days will you supply water to soil in order to ensure efficient irrigation of the given crop, if (1) Field capacity of soil =25% (2) Permanent wilting point =15% (3) Density of soil=1.5 g/cm3 (4) Effective depth of root zone= 70 cm (5) Daily consumptive use of water for the given crop=11 mm (6) Consider readily available moisture be 80% of the available moisture.
[7 marks]Give classification of irrigation canals.
[3 marks]Give classification of dams.
[4 marks]Explain the procedure of designing a channel using Kennedy’s theory.
[7 marks]Explain the procedure of designing a channel using Lacey’s theory.
[7 marks]Write down advantages and disadvantages of canal lining.
[3 marks]Explain vertical drop weir with a neat sketch.
[4 marks]An impervious floor of a weir on permeable soil is 18 m long and has sheet piles at both the ends. The upstream pile is 4.5 m deep and the downstream pile is 6 m deep. The weir creates a net head of 3 m.

[4 marks]Discuss various forces acting on a gravity dam with a neat sketch.
[7 marks]Write down functions of distributary head regulator and cross regulator.
[3 marks]Differentiate between: (1) aqueduct and super passage (2) canal syphon and syphon aqueduct.
[4 marks]Write a note on land reclamation.
[7 marks]Write a note on losses in canal.
[3 marks]Write a note on canal alignment.
