1. Canal Systems

Try these first

1. 1.

   What is a perennial canal?

   Hint

   Think about what it means for a canal to provide a constant water supply.

2. 2.

   Name one type of canal loss.

   Hint

   Consider how water can leave the canal system.

3. 3.

   What is the purpose of a perennial canal?

   • To supply water through the rainy season
   • To provide year-round water supply
   • To serve as a drainage system

   Hint

   Think of 'perennial' as year-round.

4. 4.

   True or False: Lined canals are more prone to seepage losses compared to unlined canals.

   • True
   • False

   Hint

   Consider what lining does to a canal.

5. 5.

   Design a basic canal system for a small agricultural area, considering its alignment and potential losses. Include the methods to estimate discharge.

   Hint

   Consider field shapes and types of crops when calculating discharge.

6. 6.

   Evaluate the impact of using unlined canals versus lined canals in terms of financial and water resource effectiveness for a newly planned irrigation system.

   Hint

   Think about the trade-offs between initial budget constraints and future sustainability.
