4.4. Design Parameters

Try these first

1. 1.

   What is soil infiltration rate?

   Hint

   Think about how quickly water disappears into the ground.

2. 2.

   Why is land slope important in irrigation?

   Hint

   Imagine watering a hill versus a flat area.

3. 3.

   What is the primary factor affecting how water infiltrates soil?

   • Soil type
   • Air temperature
   • Crop type

   Hint

   Think about how sandy soil behaves with water compared to clay.

4. 4.

   True or False: A steeper slope generally improves water retention in the soil.

   • True
   • False

   Hint

   Reflect on how water behaves on slopes.

5. 5.

   A field with a clay soil type has a low infiltration rate. Calculate how much time will be needed to saturate one acre of this field using a specific stream size. Consider the necessary water volume needed.

   Hint

   Use average water requirements of crops per acre to inform your calculations.

6. 6.

   Evaluate a scenario where a farmer employs irrigation on a steep slope without proper management. Discuss the potential consequences on crop yield and soil quality.

   Hint

   Consider how erosion might affect nutrient availability.
