Mugshot for First Internal Test-WRE

1.      What are the objectives of water resource development?

2.      What is irrigation? What are its necessities?

3.      What are the method of improving the Duty of water?

4.      Explain the crop seasons – Rabi and Kharif.

5.      Explain the sprinkler irrigation method and mention its advantages and disadvantages.

6.      Explain drip irrigation and mention its disadvantages.

7.      List the methods of irrigation.

8.      Explain with a neat sketch of strainer type tube well.

9.      What is a well? Mention its types.

10. Define the following

a)      Crop period

b)      Base period

c)      Duty

d)     Delta

e)      Gross Commanded Area (GCA)

f)       Cultivable command Area (CCA)

g)      Intensity of irrigation

h)      Outlet factor

i)        Kor-period

11.  Find out the capacity of reservoir if its cultivable area is 60,000 hectares, from the following data:

Type of crop	Sugarcane	Wheat	Rice
B in days	330	120	120
D in hect/cumec	2,200	1,800	800
Intensity of irrigation %	15	20	10

Assume canal losses as 6% and Reservoir losses as 10%.

12.  The duty of canal water for a tobacco crop was assumed to be 2200 hectares/cumec. First watering was done on 30^th of Nov. whereas last watering was done on 29^th March. Calculate delta for the crop. (Nov 2011 6m)
