Question Paper
What is water harvesting? Why is it essential for human survival and crop production sustainability
Differentiate between in-situ and surface water harvesting techniques. Discuss in detail any two in-situ water harvesting techniques.
What do you understand by excavated pits or ponds? How is lining helpful in reducing water losses?
Differentiate between bench terracing and contour trenching.
Define and discuss in brief roof top rain water harvesting.
Discuss in detail the different components of roof water harvesting system.
Classify the water storage tanks based on size, shape and material of construction.
Explain the process of designing of water storage tank. Discuss in detail the various steps of its design.
List the different recommended rain water harvesting structures used in central semi arid Vindhayan Zone.
What is irrigation scheduling? Explain its importance for crop production.
Define drip irrigation and describe its advantages and limitations.
Calculate the gross water storage capacity of a farm pond, if 12 cm irrigation is to be applied to 5 ha area and also meeting water requirement (for 60 days) of 50 cows and 30 buffalos. Assume water requirement of cow and buffalos as 70 and 60 litres per day.
What is plastic lining Discuss its advantages also.
What are the different methods of lining of the ponds?
How the water losses can be reduced in water supply and sanitary fittings?
Calculate the farm conveyance efficiency and field water application efficiency when a stream of 95 litres per second received at farm gate after being diverted·from a canal delivered 72 litres per second to the field.During irrigation to wheat crop for 8 hr, 350 m^3 and 158 m^3 of water respectively were lost by runoff and deep percolation.
Fill in the blanks:
Water in surface method of irrigation flows by (Pressure/ Gravity)
Contour trenching is done particularly on land with gradient having shallow soil depth.(steep/flat)
The size of water harvesting pond depends upon the amount of annual rainfall and of catchment. (length/area)
Delta is the total required by a crop during the entire period of crop growth. (volume of water/depth of water)
is an artificial application of water to the soil to enable crops to have favourable growth. (Rainfall/Irrigation)
