Day Date: Friday, 28-04-2017 Max. Marks: 70
Time: 10.30 AM to 01.00 PM
Instructions: Answer any five questions.
All questions carry equal marks.
Question 1 is compulsory
Answer any two essay question from 4.
Answer any two short note questions from 7.
Draw neat and labeled diagrams wherever necessary.
Q.1 Fill in the blanks with correct answer: 14
If a whole of topsoil is washed down, erosion is said to be
sheet erosion shelter wash off
gully erosion wind erosion
occurs under normal conditions:
Geological erosion Surface creep
Both and Accelerated erosion
Bunds, dams and drains are constructed to prevent
Stream bank erosion Sheet erosion
Slip erosion Gully erosion
is the upper surface of the zone of saturation
Water line hydroequalization gradient
aquatic differentiation margin water table
Terracing is an effective method of soil conservation:
Desert areas Hilly areas
Plains Riverine areas
Soil conservation means:
Prevention of spread of desert
To check soil erosion by wind and rains
To check soil erosion by afforestation
All of these
Deforestation may reduce the chances of:
Rain fall Frequent cyclones
Erosion of surface soil Frequent landslides
Managing watershed in forest area is/ are:
Practices for soil protection and flood control
Practices for decreasing water yield
Collection of steam orders
None of these
Page 1 of 2
Stream flow or discharges means:
It is quality of water flowing in the stream or channel
Quality, quality and timing of water yields are mostly affected by man
Both and
None of these
10) is the total length of all the streams and rivers in a drainage basin
divided by the total area of the drainage basin
Bifercation ration Drainage density
Stream frequency Drainage intensity
11) Watershed management is:
The management of watershed area to achieve certain objectives of
management
The objective can be conservation of soil and water, regulation of
stream flow regime, flood control, reduction of sediment, ground water
recharge etc.
Both and
None of these
12) If the same crop is repeatedly grown in a field:
Nitrogen starvation many result
Specific mineral deficiency may arise
Soil will become prone to diseases
Water level in soil will recede
13) If the amount of discharge in an aquifer exceeds the amount of recharge,
the groundwater table
will rise will drop
will remain the same may rise or drop depending on the porosity
14) factor will not affect the runoff
Shape of the watershed Rainfall intensity
wind direction topography
Q.2 What is Watershed? Describe the watershed development plans 14
Q.3 Discuss soil erosion. Explain the factors which affect the soil erosion? 14
Q.4 Write a note on soil and water conservation measures. 14
Q.5 Write short notes on: 14
Objectives of watershed management
Design of simple bund structure
Q.6 Explain in short 14
Land capability classification
factors affecting runoff
Q.7 Write note on 14
Rainfall pattern in India
