In which one of the following types of falls, the energy dissipation on a straight glacis remain incomplete due to vertical component of velocity remaining unaffected?
A barrage on a major river in the Gangetic plains has been designed for a flood discharge 7000 m³/s. It has been provided with a waterway of 360 m length. The looseness factor of this barrage is
Consider the following statements with respect to weir under discussion:

1. Its design corresponds to soft sandy foundation.

2. The difference in weir crest and downstream river bed may not exceed 3m.

3. When water passes over it, the longitudinal location of the formation of hydraulic jump is variable.

This weir is of the type
Two different channels, M and N, in two differend sites are designed based on Lacey's theory, to carry same quantum of discharge. But the bed material of M is found to be finer than that of N.
Assertion (A): Lining a canal is always beneficial and economical.
Reason (R): The seepage losses are greatly reduced and extra water is available for irrigation.
In order to ensure that no scouring takes place in the bed of a channel of bed slope 'S' constructed on alluvial soil of particle size 'd' m, the flow velocity should be restricted to
A tile drainage system draining 12 hectares, flows at a design capacity for two days, following a storm. If the system is designed using a drainage coefficient of 1.25 cm, how much of water will be removed during this period?
The montly consumptive use values for paddy are tabulated below. What is average monthly consumptive use?
In drip irrigation method, the drip nozzles are fixed on laterals, discharging water at a very small rate of the order of
A bridge has an expected life of 25 years and is designed for a flood magnitude of return period 100 years. What is the risk of this hydrologic design?

(a) (b)
Recorded annual maximum 24-hour rainfall magnitudes at station 'X' are as under :

What is the return period, in years, for a 6.0 cm annual rainfall according to (i) Hazen formula; and (ii) Weibull formula respectively?

2.	Glaze	b.	It is a showery precipitation in the form of irregular pellets or lumps of ice of size more than 8 mm.
3.	Hail	c.	They are frozen raindrops of transparent grains that are formed when rain falls through air at a sub-freezing temperature.
