Question

The runoff coefficient for cultivated land is generally taken as

• A. \(0.40\) to \(0.50\)
• B. \(0.51\) to \(0.62\)
• C. \(0.63\) to \(0.72\)
• D. \(0.73\) to \(0.82\)

Hint:

Runoff coefficient depends on land use and surface condition; higher values indicate more surface runoff.

Answer 1

The Correct Option is B

Concept:
Runoff coefficient is the ratio of runoff to rainfall. It depends on land use, soil type, slope and surface condition.

Step 1: Cultivated land allows some rainfall to infiltrate into the soil.

Step 2: Some part of rainfall flows over the surface as runoff.

Step 3: Therefore, cultivated land has a moderate runoff coefficient.

Step 4: For the given condition, the runoff coefficient is: \[ 0.51\text{ to }0.62 \] \[ \boxed{0.51\text{ to }0.62} \]
