Subject Name: Design Of Hydraulic Structures

Time: 02:30 PM TO 05:00 PM Total Marks: 70

Instructions:

1. Attempt all questions.

2. Make suitable assumptions wherever necessary.

3. Figures to the right indicate full marks.

Q.1 (a) Explain stability requirements of a gravity dam in detail. 07
(b) Discuss factors governing the selection of type of dam. 07

Q.2 (a) The following data were obtained from the stability analysis of a concrete
gravity dam:
Total overturning moment about toe = 1 x 10
6
kN-m
Total resisting moment about toe = 2 x 10
6
kN-m
Total vertical force above base = 50 x 10
3
kN
Base width of dam = 50 m
Slope of the d/s face = 0.8 H : 1 V
Calculate the maximum and minimum vertical stresses to which the foundation
will be subjected to. What is maximum principle stress at toe? Assume there is
no tail water.

design features of a Sarda fall.
07
(b) Why canal fall is provided in canal ? Enlist different types of fall and describe
Rapid falls.
07

Q.5 (a) What is HR and CR in the context with the canal network? Enlist function of
each with neat sketch.
07
