DIPLOMA IN WATERSHED MANAGEMENT
007 1,J
Term-End Examination
December, 2016
BNRI-103: SOIL AND WATER CONSERVATION
Time 2 hours Maximum Marks 50
Note: Attempt any five questions.
All questions carry equal marks.
Use of calculator is permitted.
Assume any realistic value for designing if
required.
1. Explain the process of soil erosion and differentiate between geological and accelerated soil erosion.
What do you mean by water erosion? What are the different types of water erosion
2. Describe the mechanism of gully formation and its different stages.
Explain the factors affecting water erosion.
3. Differentiate between Rainfall erosivity and erodibility of soil
Calculate the annual soil loss from the field subject to soil erosion problem with following observation.
Rainfall erosivity factor 800 tonnes/ha soil erodibility factor 0.2, crop management factor 0.2, conservation practice factor 0.5, and topography factor O.1. Also find out the soil loss when the cultivation is done on the contours. Assume value of conservation practice factor (contouring) as 0.2.
4. Define wind erosion and what are the causes of wind erosion
Describe process involved for transportation of soil by wind erosion.
5. Describe formation of sand dunes and list different type of sand dunes.
What are the factors responsible for wind erosion? Explain with neat sketch.
6. Differentiate between biological and artificial measures of soil erosion control.
Differentiate between contour and graded bunds and their use.
7. What do you understand by Terracing? Describe different types of bench terraces.
Explain different type of soil conservation measures applicable in the hill terrain with neat sketch diagram.
8. What do you mean by water harvesting? List different types of in-situ water harvesting techniques.
Describe various sub-surface methods of artificial ground water recharge.
