1. Modelling Infiltration Capacity

Try these first

1. 1.

   What is infiltration?

   Hint

   Think about how rainwater interacts with the ground.

2. 2.

   Name one method of measuring infiltration.

   Hint

   Consider practical tools used in the field.

3. 3.

   What is the maximum rate at which soil can absorb water called?

   • Infiltration Rate
   • Infiltration Capacity
   • Groundwater Recharge

   Hint

   Remember a term that sets a limit on absorption.

4. 4.

   True or False: Empirical models consider physical processes of infiltration.

   • True
   • False

   Hint

   Think about what these models focus on.

5. 5.

   Calculate the cumulative infiltration over a one-hour storm if the initial infiltration rate is 10mm/hour and decreases according to Horton’s model with a decay constant of 0.2.

   Hint

   Remember to apply calculus to obtain the cumulative infiltration.

6. 6.

   Discuss how climate change may influence the factors affecting infiltration in a specific region.

   Hint

   Think about how changing weather patterns influence surface conditions.
