Q: Irrigation canals are generally aligned along
  • A. Contour line
  • B. Water shed
  • C. Straight line
  • D. Valley line
Correct Answer: Option B - • Watershed canal runs perpendicular to contour line. • Irrigation canal are generally aligned along the water shed line. • It irrigating the both side of area so that CCA is large for irrigation. • The water shed line does not cross the drainage line hence cross drainage work are not required.
