Try these first

1. 1.

   What is a canal outlet?

   Hint

   Think about where water goes after the canal.

2. 2.

   Name one type of canal outlet.

   Hint

   Recall the acronym NFC.

3. 3.

   What is a characteristic of non-modular outlets?

   • A) Discharge constant at all times
   • B) Depend on upstream and downstream water levels
   • C) Suitable for precision irrigation

   Hint

   Think about the impact of water levels.

4. 4.

   True or False: Modular outlets ensure equitable distribution of water.

   • True
   • False

   Hint

   Reflect on their design features.

5. 5.

   Design a scenario where using a modular outlet would significantly improve water distribution on a farm compared to a non-modular outlet. Describe the farming conditions and illustrate the benefits.

   Hint

   Focus on variability in the environment.

6. 6.

   Evaluate the cost versus benefit of switching from a non-modular to a semi-modular outlet on a small farm. What factors would influence this decision?

   Hint

   Consider financial, environmental, and operational aspects.
