26.4.1(a). Double Ring Infiltrometer

Try these first

1. 1.

   What is the purpose of using a Double Ring Infiltrometer?

   Hint

   Think about how we measure water movement in soils.

2. 2.

   Name one benefit of using concentric rings in the Double Ring Infiltrometer.

   Hint

   Consider why lateral flow could lead to inaccuracies.

3. 3.

   What is the main purpose of the Double Ring Infiltrometer?

   • To measure evaporation rates
   • To measure infiltration rates
   • To measure precipitation

   Hint

   Think about its relation to soil and water interaction.

4. 4.

   True or False: The outer ring of the Double Ring Infiltrometer is used to control the water level in the inner ring.

   • True
   • False

   Hint

   Consider the design and function of both rings.

5. 5.

   Calculate the infiltration rate if you started with a water level of 30 cm in the inner ring and after 1 hour, it dropped to 15 cm. What is the rate of infiltration in cm/hr?

   Hint

   Think about the change in water level over time.

6. 6.

   Discuss the potential impacts of an inaccurate infiltration measurement in agricultural planning and soil conservation efforts.

   Hint

   What happens if farmers misjudge how much water their soil can absorb?
