Canal outlet helps in:

If the net irrigation requirement is 8 cm and water application efficiency is 80 %, then water depth required to be applied in the field will be

An outlet irrigates an area of 20 hectares. The discharge (in cumec) required at this outlet to meet the evapotranspiration required of 86.40 mm occurring uniformly in 20 days neglecting other field losses is.

In regime channel the discharge is 16 m³/s if depth of flow is 1 m then according to Lacey’s theory width of the trapezoidal channel for side slope 1H:1V is

What will be the frequency of irrigation, if allowable depletion depth between irrigation is 15 mm and the daily water used by crop is 3 mm/day?

A canal irrigates a portion of a culturable command area to grow sugarcane and wheat. The average discharge required to grow sugarcane and wheat are 1 cumec and 0.6 cumec respectively. The time factor is 0.8. The required design capacity of the canal is

A launching apron is to be designed at downstream weir for discharge intensity of 8 cumec/meter. For the design of launching aprons the scour depth is taken two times of lacey scour depth. The silt factor of bed material is unity. If the tail water depth is 4.8 m, the length of launching apron in the launched position is

Acidic soils are reclaimed by

For the augment supplies in canal water through a hydraulic structure is joined by the drainage water, this system is known as
