What does the Thiessen polygon method calculate?
Average rainfall
Stream discharge
Hydrometer measurements
Surface runoff
Correct answer
Average rainfall
What is the significance of the base flow in hydrograph analysis?
It represents the total runoff
It is the part of the runoff that remains constant over time
It is the portion of runoff due to groundwater
It helps in determining the peak discharge
Correct answer
It represents the total runoff
The time of concentration of a catchment depends primarily on:
Average annual rainfall only
Length and slope of the longest travel path and surface roughness
Mean air temperature
Type of rain gauge used
Correct answer
Average annual rainfall only
In a triangular channel, the top width and depth of flow are 2. 0 m and 0. 9 m, respectively. What is the discharge in the channel if the velocity measurements indicated velocities of 0. 60 \(m/s\) and 0. 40 \(m/s\) at 18 cm and 72 cm below the water surface?
Correct answer
In a river carrying a discharge of \(142 \text{ m}^3/\text{s}\), the stage at a station A is \(3.6 \text{ m}\), and the surface slope is \(1 \text{ in } 6000\). If during a flood, the stage at A is \(3.6 \text{ m}\), and the surface slope is \(1 \text{ in } 3000\), what was the flood discharge approximately?
\(284 \text{ m}^3/\text{s}\)
\(200 \text{ m}^3/\text{s}\)
\(164 \text{ m}^3/\text{s}\)
\(96 \text{ m}^3/\text{s}\)
Correct answer
\(284 \text{ m}^3/\text{s}\)
A stream has a cross-sectional area of \(100\ m^2\), a velocity of \(3\ m/s\), and a roughness coefficient of \(0.03\). Calculate the discharge of the stream.
Given:
Area = \(100\ m^2\)
Velocity = \(3\ m/s\)
Roughness coefficient = \(0.03\)
\(300\ m^3/s\)
\(208\ m^3/s\)
\(120\ m^3/s\)
\(234\ m^3/s\)
Correct answer
\(300\ m^3/s\)
