Estimating and Costing - Engineering

Q1:

Pick up the correct statement from the following:

A 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.)

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

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

D 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

E All the above.

ANS:E - All the above.

When NSL is between FSL and Bed level. The canal is fully in cutting.
