Which irrigation method is best suited for orchards?

In which type of canal is only one side of the canal irrigated?

An unlined irrigation channel has a discharge of 2.5 m³/sec/m and a silt factor of 1. Find the scour depth using Lacey's equation.

In which of the following flooding methods is water supplied to the basin through a supply ditch?

The intensity of irrigation for Rabi season is 50% and for Kharif is 30%. The gross command area is 30,000 ha, out of which 70% is culturable command area. Find the crop ratio.

What is the gross irrigation requirement of a crop if the application efficiency is 65% and the water conveyance efficiency is 60%, and the net irrigation requirement of the crop is 12 cm?

At a certain point in the floor of a weir, the uplift pressure head due to seepage is 5 m. If the relative density of concrete is 2.5, what is the minimum thickness of the floor required at this point to counteract the uplift pressure?

Consider the following statements about Stream Flow Routing:

1) Prism storage depends only on the flood outflow.

2) Wedge storage depends on the difference between inflow and outflow.

3) Prism storage routing is aided by the Muskingum method.

Which of the above statements is/are correct?

The data for an agricultural field for a specific month are given below:

Pan Evaporation = 100 mm

Effective rainfall = 20 mm (after deducting losses due to runoff and deep percolation)

Crop coefficient = 0.4

Irrigation efficiency = 0.5

The amount of irrigation water (rounded in mm) to be applied to the field in that month, is

The command area (CCA) of a watercourse is 1500 hectares. The cropping intensity of sugarcane and wheat crops is 20% and 40% respectively. The duties for the crops at the head of the watercourse are 730 hectares/cumec for sugarcane and 1600 hectares/cumec for wheat. Calculate the design discharge at the outlet, assuming a time factor of 0.8.
