27.4. Measurement of Infiltration

Try these first

1. 1.

   What is the function of an infiltrometer?

   Hint

   Think about what instruments do in terms of measurement.

2. 2.

   Name one type of infiltrometer.

   Hint

   Recall the instruments we discussed.

3. 3.

   What is the primary function of an infiltrometer?

   • To measure rainfall
   • To measure water infiltration
   • To measure soil temperature

   Hint

   Think about the purpose of measuring water movement into soil.

4. 4.

   True or False: A double ring infiltrometer is more accurate than a single ring infiltrometer.

   • True
   • False

   Hint

   Consider the design differences of the two instruments.

5. 5.

   If a rainfall simulator indicates that 70% of water applied is absorbed by the soil in an experimental setup, what could be the implications for agricultural practices in the region?

   Hint

   Think about how infiltration affects crop watering needs.

6. 6.

   Discuss how using both a lysimeter and a double ring infiltrometer could provide complementary data when studying infiltration. What might each method reveal that the other cannot?

   Hint

   Consider how direct and indirect methods work together.
