Question:
The design velocity of flow in a grassed waterway is 2.0 m/s, then the cover condition should be:
The design velocity of flow in a grassed waterway is 2.0 m/s, then the cover condition should be:
Show Hint
Dense vegetation stabilizes grassed waterways, preventing erosion at high velocities.

- Good Grass Cover
- Sod of Excellent Cover
- Sparse Grass Cover
- No Vegetation
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Grassed Waterways
Grassed waterways prevent soil erosion by slowing down runoff.
Step 2: Evaluating Cover Conditions
- Good grass cover: Supports moderate flow. - Sod of excellent cover: Supports high-velocity flow (2.0 m/s). - Sparse grass cover: Unsuitable for high velocity. - No vegetation: Leads to erosion.
Step 3: Conclusion
For 2.0 m/s flow, sod of excellent cover is needed.
