A stream of 135 L/s was diverted from a canal and 100 L/s were delivered to the field. An area of 1.6 hectares was irrigated in 8 hours. The effective depth of root zone was 1.8 m. the runoff loss in the field was 432 m3. The depth of water penetration varied linearly from 1.8 m at the head end of the field to 1.2 m at the tail end. Available moisture holding capacity of the soil is 20 cm per meter depth of soil. Irrigation was started at a moisture extraction level of 50 percent of the available moisture. Determine; a. The water conveyance efficiency b. The water application efficiency c. The water storage efficiency d. The water distribution efficiency

Question
A stream of 135 L/s was diverted from a canal and 100 L/s were delivered to the field. An area of 1.6
hectares was irrigated in 8 hours. The effective depth of root zone was 1.8 m. the runoff loss in the field
was 432 m3. The depth of water penetration varied linearly from 1.8 m at the head end of the field to
1.2 m at the tail end. Available moisture holding capacity of the soil is 20 cm per meter depth of soil.
Irrigation was started at a moisture extraction level of 50 percent of the available moisture. Determine;
a. The water conveyance efficiency
b. The water application efficiency
c. The water storage efficiency
d. The water distribution efficiency
