1. 'Drift' is the material picked up, mixed, disintegrated, transported, and repositioned by

2. The types of soil, which contain particles of almost the same size

3. If s is the focal length of Kozeny's parabola and k is the coefficient of permeability, the seepage flow rate per unit length of the dam is given as

4. Angle of Internal friction is minimum for

5. Shear strength of a soil is a unique function of

6. Clays containing organic matter are made suitable for stabilization by first adding a small percentage of

7. The seepage force is proportional to

8. The factor of safety of slopes is defined as:

9. Overturning moment due to the pressure of the soil is 10 KN-m while the resisting moment is 5 KN-m. Find the factor of safety:

10. The ratio of volume of voids to the total volume of the given soil mass is known as

11. Cohesion is defined as:

12. The internal molecular attraction of a soil is known as cohesion:

13. Sheet piles are held in position by:

14. The minimum water content at which the soil just begins to crumble when rolled into threads 3 mm in diameter is known as

15. The minimum net pressure intensity causing shear failure of the soil is called:

16. The degree of saturation in soils can be defined as the ratio of

17. If in a partially saturated soil, the degree of saturation is 40%, then the air content of the soil is

18. Contribution due to skin friction is maximum in:

23. In a sand stratum of 1.5m thickness, specific gravity 2.67, and voids ratio 0.67, the head required for the quick condition is equal to

24. * A 'shear stress' is a stress which is applied.......to a face of material.

25. A vertical wall is subjected to a liquid pressure on its one side, the total pressure on the wall acts at a distance of:

26. The bearing capacity of a soil depends upon:

27. Rise of water table in cohesionless soils up to the ground surface reduces the net ultimate bearing capacity approximately by:

28. A fully saturated soil is called

29. Flow lines and equipotential lines are

30. Generally, soils are considered as
