29. What is the primary objective of applying Lacey's regime theory in irrigation engineering?

1. Minimize water consumption
2. Ensure hydraulic efficiency
3. Prevent channel erosion
4. Maximize crop yield

Answer

The correct answer is: C) Prevent channel erosion

Explanation

Lacey's regime theory aims to prevent channel erosion by designing irrigation channels that maintain stable flow regimes, thereby minimizing the risk of erosion and sedimentation.
