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

The water which can be utilized by the crops from the soil is called

Water conveyance efficiency is given as:

If the discharge required for different crops grown in the field is 0.4 cumecs, and the capacity factor and time factor are 0.8 and 0.5, the design discharge for the distributary will be:

Critical velocity ratio for use in Kennedy’s theory is:

As per Lacey’s regime equation, what is the flow velocity proportional to?

The normal annual rainfall of the stations A, B, C and D in a catchment is 82 mm, 91 mm, 85 mm, and 90 mm respectively. In the year 2007, the station D was inoperative when stations A, B and C recorded annual rainfall of 91 mm, 72 mm and 80 mm. Estimate the missing rainfall at station D in the year 2007.

A stream of 150 liters per second was delivered from a canal and 120 per second were delivered to field. The depth of water penetration varied linearly from 2 m at the head end of the field to 1.2 m at the tail end. Available moisture holding capacity of the soil is 200 mm per metre depth of soil. What will be the water distribution efficiency?

If discharge through a channel is 1600 cumec. Then according to Lacey’s theory wetted perimeter can be
