Q: Why do we need to do the lining of the canal A. To minimize seepage losses in canal B. to prevent erosion of bed and sides due to high velocities C. To decrease the discharge in the canal section by increasing the velocity
  • A. Only A
  • B. Only A and B
  • C. Only C
  • D. All A, B and C
Correct Answer: Option B - Lining of canal– To minimize the losses due to seepage. • To prevent the area prone to water logging due to rise in water table. • To increase the discharge capacity of the canal. • Improvement of command and larger working head for power generation. • To prevent erosion of bed and sides due to high velocities.
