26.4. Measurement of Infiltration

Try these first

1. 1.

   What is an infiltrometer used for?

   Hint

   Think about what we measure in soils.

2. 2.

   Explain the basin method in simple terms.

   Hint

   Consider the idea of filling a cup and measuring how fast the water level goes down.

3. 3.

   What is the primary purpose of using an infiltrometer?

   • To capture rainfall data
   • To measure infiltration rates
   • To assess soil temperature

   Hint

   Think about what we want to quantify in soils.

4. 4.

   True or False: The single ring infiltrometer is more accurate than the double ring infiltrometer.

   • True
   • False

   Hint

   Remember which method reduces side effects more.

5. 5.

   You are tasked with measuring infiltration rates in a newly developed residential area with mixed soil types. Which infiltration methods would you choose, and why?

   Hint

   Consider the accuracy needed for your final results.

6. 6.

   During a rain event, you measure the soil moisture before and after and find a significant increase. How would you interpret this data in terms of infiltration capacity?

   Hint

   Think about how absorption rates relate to precipitation.
