13. Modeling Infiltration Capacity

Try these first

1. 1.

   What is the equation for Horton's Model?

   Hint

   It involves initial and final rates.

2. 2.

   What does Philip's Model take into account?

   Hint

   Look for terms like conductivity and sorptivity.

3. 3.

   What does Horton's model express?

   • Constant rate of infiltration
   • Decreasing infiltration rate over time
   • Infiltration based on temperature

   Hint

   Concept of changing rates in relation to water absorption.

4. 4.

   Is the Green-Ampt Model physically based?

   • True
   • False

   Hint

   Think about its design purpose.

5. 5.

   Calculate the infiltration capacity using Horton's model with given parameters: initial rate = 30 mm/hr, final capacity = 10 mm/hr, and k = 0.05 hr^-1 after 4 hours.

   Hint

   Use the formula's structure to plug in your numbers correctly.

6. 6.

   You are designing a drainage system for a sandy soil region. Describe how you would select an infiltration model and why.

   Hint

   Focus on how soil texture influences water movement decisions.
