- Pick up the incorrect statement from the following:
- A deficit of sediments in flowing water may cause a river
- Which one of the following statements is correct?
- Cyclonic precipitation is caused by lifting of an air mass due to
- If the height of the hydraulic gradient line above the floor of thickness t is h and the specific gravity of the material of the floor is G, the minimum thickness t of the floor downstream of the crest-wall, is given by the equation
- Side slopes generally kept for canals in loam soil, are:
- 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
- The most suitable location of a canal head work, is
- Cross regulators in main canals are provided
- Process of meandering is due to

D.
None of these |
A.
The canal system and the drainage system are complementary |
B.
