Question 1

Super passage is a canal cross-drainage structure in which

Question 2

The net uplift force on a dam if the height of water in the reservoir is 45 m. (Assume the width of the dam to be 21m)

Question 3

The following figure shows the section of hydraulic structure formed on sand.

Find the uplift pressure at point C which is 18 m from the upstream end of the floor.

Question 4

Design a channel section as per Lacey’s theory using following data
Discharge Q = 8 m³/sec
Silt factor f = 1.2
Side slope = 1/2 H: 1V
Match List-I with List-II & select correct answer using the codes given below

Question 5

A concrete dam having width 14m and height 17.45m is constructed on a river to store water. If the compressive strength and the specific gravity of concrete is 2896 kN/m² and 2.24 respectively, then what will be the critical height of the dam? Also classify the dam based on its height.

Question 6

In a cultivated area, the soil has porosity of 45% and field capacity of 38%. For a particular crop, the root zone depth is 1.0 m, the permanent wilting point is 10% and the consumptive use is 15 mm/d. If the irrigation efficiency is 60%, what should be the frequency of irrigation such that the moisture content does not fall below 50% of the maximum available moisture ?
