Most commonly used non-recording type rain-gauge is:
A)
Weighting bucket
B)
Symon’s rain-gauge
C)
Tipping bucket rain-gauge
D)
Floating type rain-gauge.
Symon's rain gauge is the standard non-recording rain gauge.
The true bearing of a line is 34º20’40" and the magnetic declination at the place of observation is 2º00’20" on the date of observation, then the magnetic bearing of the line is:
A)
36º 21’ 00"
B)
32º 00’ 20"
C)
32º 20’ 20"
D)
34º 20’ 20"
The correct choice is B: this follows from standard civil-engineering surveying/structural/concrete principles for the stated condition.
The type of surveying in which the curvature of earth is taken into account is called:
A)
geodetic surveying
B)
plan surveying
C)
preliminary survey
D)
topographical survey
Geodetic surveying accounts for the curvature of the earth.
The hydrologic flood routing methods are:
A)
Equation of continuity only
B)
Equation of motion only
C)
Both momentum and continuity equations
D)
Energy equation.
Flood routing is based on conservation of mass/continuity together with momentum or storage relations; among the choices, both are involved.
Most common type of self recording gauge is:
A)
Weighing bucket
B)
Symon’s rain-gauge
C)
Tipping bucket type
D)
Float type automatic rain gauge.
The tipping-bucket type is a common self-recording precipitation gauge.
For construction of grassed waterways the land slope should be:
A)
Less than 20%
B)
5-10%
C)
10-15%
D)
20-30%
Grassed waterways are generally laid on moderate slopes, with 5–10% being a common design range in such questions.
