Subject Code: 180601 Date: 15/05/2019
Subject Name:Design Of Hydraulic Structures
Time: 10:30 AM TO 01:00 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) Discuss in brief earthern dam and rockfill dam. 07
(b) Describe the factors governing the selection of site for a dam. 07
Q.2 (a) Describe hydraulic and seepage failure of earthen dam. 07
(b) A flow-net is plotted for homogeneous earthen dam of height 22 m and free board
2 m. Number of potential drops and flow channels are 10 and 4 respectively. The
dam has a horizontal filter of 30 m length at a downstream end and the coefficient
of permeability of the dam material is 5 x 10
-4
cm/sec. Calculate the discharge
per m run of the dam.
07
OR
(b) Describe Swedish slip circle method for analysis of Embankment Dam. 07
Q.3 (a) Enlist the various forces acting on gravity dam and discuss in detail water
pressure and uplift pressure.
07
(b) Describe stability analysis of gravity dam by graphical method. 07
OR
Q.3 (a) Explain Inspection gallery and Construction joints in gravity dam. 07
(b) A concrete gravity dam (Non-overflow section) is given in Figure A on page 2.
Compute the following: (1) Water Pressure (2) Weight of dam and (3) Wave
Pressure. Consider specific weight of Concrete = 24 kN/m
3
, Fetch = 12 km, Wind
velocity = 80 kmph and ?h = 0.1 g
07
Q.4 (a) Explain mode of failure of a gravity dam. 07
(b) Write short note on Ogee Spillway. 07
OR
Q.4 (a) Write short note on Bucket type Energy Dissipators. 07
(b) Compute the discharge over an ogee weir with coefficient of discharge equal to
2.4 at a head of 2 m. The length of spillway is 100 m. The weir crest is 8 m above
the bottom of the approach channel having the same width as that of the spillway.
Consider velocity of approach.
07
Q.5 (a) What is canal fall? Why is it required to provide in a canal? 07
(b) How can seepage be controlled in earth dams? 07
OR
Q.5 (a) Discuss various functions of cross regulator and distributary head regulators. 07
(b) Explain design of Sarda Fall. 07
