[#121] Side slopes generally kept for canals in loam soil, are:
Correct Answer
(D) Both (A) and (B)
[#122] 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
Correct Answer
(A) aqueduct
Explanation
Solution: 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.
[#123] The most suitable location of a canal head work, is
Correct Answer
(D) Trough stage of the river
[#124] Cross regulators in main canals are provided
Correct Answer
(B) To increase water head upstream when a main canal is running with low supplies
[#125] Process of meandering is due to
Correct Answer
(D) All the above
