28.7. Limitations and Sources of Error

Try these first

1. 1.

   What is lateral flow error?

   Hint

   Think about how water can move in different directions.

2. 2.

   Name one source of error from human activities.

   Hint

   Consider how measurements might differ if someone makes a mistake.

3. 3.

   What is a common source of error when using a single ring infiltrometer?

   • High evaporation
   • Lateral flow error
   • User error
   • Soil temperature

   Hint

   Think about how water moves in different directions.

4. 4.

   True or False: Evaporation losses are negligible in short infiltration tests.

   • True
   • False

   Hint

   Consider the duration of the test and its impact on water loss.

5. 5.

   Design an infiltration test plan for a site with known soil heterogeneity, ensuring error minimization.

   Hint

   How can you ensure accuracy despite the mix of soil types?

6. 6.

   Evaluate a situation where human error significantly impacted infiltration measurements. What strategies could have prevented this?

   Hint

   Think about what could help reduce reliance on manual observations.
