Channel Bed Slope and GVF Profiles
Channel bed slope and GVF (Gradually Varied Flow) profiles have a direct relationship. The GVF profile is the variation of water surface elevation along the channel length.
- If the channel bed slope is mild, the GVF profile will be M1.
- If the channel bed slope is steep, the GVF profile will be M2.
GVF Profiles for Mild and Steep Slope
- Mild Slope (M1) GVF Profile: In mild slope, the water surface elevation gradually increases along the channel length. The GVF profile is concave in upward direction.
- Steep Slope (M2) GVF Profile: In steep slope, the water surface elevation increases rapidly along the channel length. The GVF profile is convex in upward direction.
GVF Profiles for Different Slopes
- S2 GVF Profile: If the channel bed slope changes from mild to steep, the resulting GVF profile will be M2, S2. This means that the water surface elevation will increase rapidly along the channel length and the GVF profile will be convex in upward direction.
- S1 GVF Profile: If the channel bed slope changes from steep to mild, the resulting GVF profile will be M1, S1. This means that the water surface elevation will gradually increase along the channel length and the GVF profile will be concave in upward direction.
Correct Answer
The given question states that the channel bed slope changes from mild to steep. Therefore, the resulting GVF profiles will be M2, S2. Hence, the correct answer is option 'C'.

Correct Answer
The given question states that the channel bed slope changes from mild to steep. Therefore, the resulting GVF profiles will be M2, S2. Hence, the correct answer is option 'C'.
