16. Which of the following factors is most likely to attenuate the peak flow in a flood hydrograph?
- Increased channel roughness
- Higher precipitation intensity
- Reduced basin area
- Enhanced soil infiltration capacity
Answer
The correct answer is: D) Enhanced soil infiltration capacity
Explanation
Increased soil absorption capacity lowers runoff volume and attenuates the peak flow in a flood hydrograph by facilitating increased water absorption.
