The culturable command area for a distributary channel is 20,000 hectares. Wheat is grown in the entire area and the intensity of irrigation is 50%. The kor period for wheat is 30 days and the kor water depth is 120 mm. The outlet discharge for the distributary should be
-
- 2.85 m³/s
- 3.21 m³/s
- 4.63 m³/s
- 5.23 m³/s
Correct Option: C
Effective area to be irrigated = 20000 × 50% = 10000 hectares
Kor period = 30 days(Period of irrigation)
Kor depth = 120 mm
Volume of water = 10000 × 10–4 × 120 × 10–3
| Discharge, Q = | (days to seconds) = 4.63 m³/s. | |
| 30 × 24 × 60 × 60 |
