Pick up the correct statement from the following:

If the bed level is above N.S.L. the canal is called fully in baking and the berms are designed as 3 d where d is full supply depth of water (F.S.D.)

Area of canal in cutting = BD + Sd² where B = bed width, d = depth of cutting and S is the side slope

Area of the bank of canal = B₁d₁ + Sd₂ where B₁, d₁ and S are the width of bank, height of the bank above N.S.L. and side slope respectively

If F.S.L. is above N.S.L the canal is called partly in cutting and partly in filling and berms are designed as 2d where d is full supply depth

All the above.

[#]

19.

Consider the following statements relating to triaxial tests :
1. Change in length of the specimen in a triaxial shear test is required to be accounted for in the calculation of stresses at failure.
2. In 'Drained Triaxial Shear Test', drainage is permitted under a specified all-round pressure until consolidation is complete. The principal stress difference is then applied with no drainage being permitted.
3. Unconfined compression test is a special case of triaxial shear test.
Of these statements :

1 and 2 are correct

1 and 3 are correct

2 and 3 are correct

1, 2 and 3 are correct
