39.5. Factors Affecting Duty

Try these first

1. 1.

   What factor reduces duty when using sandy soil?

   Hint

   Think about how water moves through different soil types.

2. 2.

   Name a high water-demand crop.

   Hint

   Consider crops that typically need a lot of water.

3. 3.

   What effect does sandy soil have on irrigation duty?

   • Increases duty
   • Decreases duty
   • No effect

   Hint

   Think about how water behaves in sandy soils.

4. 4.

   True or False: High water-demand crops will likely increase duty.

   • True
   • False

   Hint

   Reflect on crop water needs.

5. 5.

   A farmer has sandy soil and grows rice. Detail the impact on his irrigation duty, and suggest adjustments to improve his irrigation system.

   Hint

   Consider both the soil's properties and effective irrigation methods.

6. 6.

   Evaluate the irrigation system design for a region with high topography differences and suggest improvements to increase duty.

   Hint

   Think about practical engineering solutions to tackle the topography challenge.
