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. 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
D. All the above
