Indian Forest Service (IFS) Main Exam Agricultural Engineering Question Paper

SECTION A
1. Answer each. of the following :
What are the main causes of soil erosion in India? Explain the agronomic practices adopted for controlling the soil erosion.

What are the contour and graded bunds? How do they differ in design and functional aspects?

Calculate the cross-section of a contour bund used to store 24-hour excess rainfall of 10 em. The annual rainfall is about 120 em with a high intake rate and there is low coverage of crops over the land. The land slope is 4%. Use Cox's formula for VI of contour bund.

2 . With a neat sketch, explain the working of drop inlet spillway. Under what situation is it preferred?

What are the main objectives of watershed management programme? What survey is required to be conducted while planning for watershed development?

Design the dimensions of a weir used to discharge excess runoff through a contour bund for the conditions given below :
Land slope = 1 • 5%
Top width of the bund = 45 em
Height of the bund = 60 em
Height of crest above GL = 30 em
Side slope of the bund = 2 : 1
VI =1m
Length of the bund = 400 m
Intensity of rainfall for the retum period and time of concentration = 12 cmjhr
During the peak rainfall constant infiltration rate = 2 • 5 cmjhr
No water is stored behind the bund before the peak rainfall occurs
Determine the volume of water stored behind the bund before it starts flowing.

3. Describe in brief the runoff inducing practices for increasing runoff for water harvesting.

Define rational formula for estimating peak runoff rate. Why is it called rational? What are the limitations of rational formula?

Design a 150 m long inward sloping (5%) bench terrace for a sandy loam soil with an average slope of 15%. The entire width of the terrace acts as a channel which is provided with a uniform grade of 0 •6%. The rainfall intensity for the return period and time of concentration is 20 cm/hr, runoff coefficient = 0 • 3, riser side slope = 1: 1, shoulder bund height = 30 em, bottom width = 75 em, side slope = 1 : 1, Manning's n = 0 • 04, VI= 1• 06 m, area of the terrace = 0 • 09 ha.

4. Classify remote sensing based on type of data acquisition. Explain in brief the application of remote sensing in agriculture and forestry.

What is water-stage recorder? Discuss the current meter as a water flow measuring device.

Design a parabolic shaped grassed waterway to carry a flow of 3 cu m/s down a slope of 4%. An excellent stand of dub grass is to be maintained in the waterway. Take Manning's n = 0 • 04.
