Question

A drainage canal discharges 0.2 m$^3$/s and drains 250 ha. The drainage coefficient of land is

• A. 0.52 cm
• B. 6.90 cm
• C. 0.69 cm
• D. 0.43 cm

Hint:

A handy shortcut formula for Drainage Coefficient (\( D_c \) in cm/day) is:
\( D_c = \frac{8.64 \cdot Q}{A_{\text{ha}}} \times 100 \).
Using our values: \( D_c = \frac{8.64 \cdot 0.2}{250} \times 100 = 0.6912 \text{ cm/day} \).

Answer 1

The Correct Option is C
