F.AQ in IRRIGATION

Hi Everybody!
What are the Frequently Asked Questions in IRRIGATION? this may be your Question.
Here are Some .
1) What is irrigation? It is the artificial supply of water to the field for thwe growth of plants .
2)What is the need for irrigation? what are the benefits ?
3) What are the different sources of irrigation ? Explain in detail
4) What are the different Methods of irrigation .Explain with neat sketches .and advantage and disadvantages of each one.
Explain in detail the scope of development in India and history of development of irrigation in India.
5)Write the concept of duty and what are the factors affecting duty?
6) what are the difference between duty and delta explain in detaial. now you have covered almost all FAQ in unit I .Irrigation as a science

Now coming to UNIT-2 Crop water requirement .
It is the portion most of the irrigation engineers don't give importance as they think it is the duty of Agriculture officers and agricultural engineers to worry about. But it is very important for a civil engineer to know something about CROP_SOIL_WATER relation ship.
What is EVAPO_TRANSPIRSATION ? What do you understand by consumptive use ?How will you assess the crop water requirement ? What do you understand by GIR,NIR,? What is effective rainfall? What do you understand by Precipitation ? discuss in detail about the water cycle or hydro-logical cycle.
what do you understand about water-logging ? how to remedy it?
 NEXT ......
CONVEYANCE AND DISTRIBUTION OF IRRIGATION WATER   effeciently is the main duty of an IRRIGATION ENGINEER.
What is a Head work? What are the important diversion and storage works ? How a canal is designed .What are the design formulae?
What do you understand about the distribution system -Main canal,Branch canal, Distributory,Field channel ,watercourses,Minor distributery etc.. ?
What do you understand by CD works and CM works? Give examples of Cross drainage works .
Name some of Cross masonry works .
differentiate between superpassage and undertunnel.
Aqueduct and siphon aqueduct. Culvert and bridge

IT is very important for an engineer to be a Manager also. WATER MANAGEMENT is needed now adays as the supply and demand doesnot match.
What is the need for optimising water use?
How to improve productivity of crop with unit quantity of water?
How to minimise the loss of water in irrigation?
What are the physicasl structures used to control the supply of water to land ?
Why operational rules and regulations needed ?
What do you know about WUA(Water Users Association)?
What do you understand about PIM (PARTICIPATORY IRRIGATION MANAGEMENT)?
What are the advanTAGES OF LINING CANALAL ? WHAT ARE THE DIFFERENT TYPES OF LINING?

NEXT BECOMES THE VERY IMPORTANT CHAPTER .
DESIGN OF STRUCTURES .
WHAT ARE THE CAUSES OF FAILURE OF AN EARTHEN DAM /? HOW WILL YOU DESIGN AN EARTHEN DAM .
WHAT DO YOU UNDERSTAND BY PIPING? HOW TO AVOID IT?
WHAT ARE THE DIFFERENT TYPES OF DAMS .HOMOGENEOUS AND ZONED .WHAT DO YOU UNDERSTAND .EXPLAIN WITH NEAT SKETCH.
WHAT IS BLIGHES THOERY .HOW WILL YOU DESIGN A WEIR?
WHAT ARE THE DESIGN CRITERIA OF DESIGNING A SIMPLE MASONRY DAM?
THEN
PROBLEMS ? wORKED OUT NUMERICAL PROBLEMS . oNCE YOU ARE THOUROUGH ABOUT FORMULA IT IS EASY TO SOLVE .
NOW YOU FIND OUT ANSWERS FOR THESE  FREQUENTLY ASKED QUESTIONS .
WISH YOU ALL GRAND SUCCESS IN YOUR EXAMINATIONS.
