31.1. Infiltration Concept Recap

Try these first

1. 1.

   Define infiltration capacity.

   Hint

   Think about what the soil can handle at once.

2. 2.

   What does cumulative infiltration indicate?

   Hint

   Consider the time aspect of water absorption.

3. 3.

   What is infiltration capacity?

   • Maximum rate of water absorption
   • Current water absorption rate
   • Total water absorbed over time

   Hint

   Think about what soil can handle best.

4. 4.

   True or False: Cumulative infiltration is only important during heavy rainfalls.

   • True
   • False

   Hint

   Consider various water conditions.

5. 5.

   You have a soil that can absorb water at a rate of 25 mm/hr and a rainfall of 40 mm/hr occurs. Calculate the amount of runoff generated if the rainfall lasts for 2 hours.

   Hint

   Calculate the difference between rainfall and infiltration capacity.

6. 6.

   Propose a method for measuring cumulative infiltration after a storm event in a field, considering factors that might influence your data collection.

   Hint

   Consider practical tools and challenges specific to the environment.
