28.5. Analysis of Infiltration Data

Try these first

1. 1.

   What does cumulative infiltration represent?

   Hint

   Think about it as the total water absorbed.

2. 2.

   Name one empirical formula used in infiltration data analysis.

   Hint

   It relates to how the infiltration rate changes over time.

3. 3.

   What is the main purpose of plotting infiltration rate vs time?

   • To determine cumulative infiltration
   • To assess soil temperature
   • To analyze runoff potential

   Hint

   Consider why we track absorption over time.

4. 4.

   Horton’s equation is primarily used to describe...

   • True
   • False

   Hint

   Focus on its purpose in analyzing infiltration.

5. 5.

   Given a dataset of infiltration rates over time, describe how you would determine the steady-state infiltration rate and its implications for groundwater recharge.

   Hint

   Focus on identifying trends in the plotted data.

6. 6.

   A soil sample shows high initial infiltration rates that quickly decline. Discuss how this behavior impacts irrigation planning for crops.

   Hint

   Relate it to crop water requirements and timing of water application.
