PART A
1. Define Juvenile and Connate water?
2. Write a note on well loss.
3. State Darcy’s law and its application.
4. What do you mean by cavity tube well?
5. What are the factors controlling the ground water?
PART B
1. Discuss the different types of aquifers and its geological formation.
2. Write a brief note on ground water occurrence and distribution in our country.
(or)
Explain the various water bearing properties of rock.
3. How the velocity of ground water movement is determined by using empirical formula, field measurement and Darcy’s law?
(or)
Explain the determination of permeability in the laboratory?
4. Design a tube well to deliver 6256 litters per day at a depression head of 5m. The average water level is 10m below the ground in October and 15m in July. The geological investigations have yielded the following results at the site of boring:
Depth Type of strata
0 - 5m surface clay
5 - 20m very fine sand
20 - 30m clay with kankar
30 - 50m coarse sand
50 - 60m clay
60 - 70m medium sand
Below 70m clay with sandstone.
(or)
Explain the design principles considered in well screen.
5. Explain briefly the artificial recharge methods of increasing ground water potential.
(or)
Describe water level fluctuation method and explain how annual replenishable water potential is calculated.
