If the R.L’s of canal bed level and high flood level of drainage are 212.0 m and 210.0 m respectively, then cross drainage work will be
Answer & Solution
Correct Answer:
Option
A
An aqueduct is a type of cross drainage work where the canal passes over the drainage.
In this case, the R.L. (Reduced Level) of the canal bed is higher at 212.0 m compared to the high flood level of the drainage at 210.0 m.
This difference in levels makes an aqueduct the appropriate structure, allowing the canal to safely cross above the drainage.

LoginBecause the R.L is measured on Staff with reference to a benchmark.
so low reading on staff means high elevation so ultimately 210 HFL of dranige will be higher than 212 of canal bed.
so Syphon need to be provided
A is correct
