Calculate the value of maximum scour depth for a single span structure having normal scour depth 5m.

Calculate the value of maximum scour depth for a single span structure having normal scour depth 5m. Correct Answer 7.5 m

The factor of safety for single-span structure on a straight reach of the stream is generally taken as 1.5 and is taken as 2.0 for multi-span structures. Maximum scour depth = 1.5 x 5 = 7.5 m.

Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador.
