Which of the following is / are the Ideal Bridge Site Characteristic(s)? i. The flow of water in the stream at the bridge site should be in steady regime condition ii. The stream should be well defined and as narrow as possible iii. There should be confluence of large tributaries in the vicinity of bridge site
- AOnly (i)
- B(i) and (ii)Correct
- C(ii) and (iii)
- D(i), (ii) and (iii)
Solution
Concept
Ideal bridge site
Step-by-step solution
1. An ideal site has steady regime flow and a well-defined, narrow stream. 2. A confluence of large tributaries causes erratic flow and is undesirable.
Explanation
An ideal site has steady regime flow and a well-defined, narrow stream.
Why the other options are wrong
Options with (iii) include an unfavourable condition.
Correct answer: B) (i) and (ii)
