Question 1

What does Horton’s Equation model?

  • Initial infiltration rates
  • Declining infiltration rates over time
  • Cumulative infiltration values

💡 Hint: Think about how infiltration changes from the start of rain.

Question 2

True or False: Philip's Equation does not consider the effect of gravity.

  • True
  • False

💡 Hint: Recall how water naturally behaves under the influence of gravity.

Challenge Problems

Push your limits with challenges.

Question 1

Given a soil with a hydraulic conductivity of 15 mm/hr, a saturated moisture content of 30%, and an initial moisture content of 10%, use Green-Ampt Equation for a ponded situation to find cumulative infiltration after 2 hours. Show all calculations.

💡 Hint: Set up the equation with the known variables, prioritize calculating suction head and subsequent infiltration.

Question 2

A drainage engineer finds that a field's infiltration rate starts at 100 mm/hr and stabilizes at 20 mm/hr. Create a scenario using Horton’s Equation to calculate the decay constant, k, after the first three hours. Provide detailed reasoning.

💡 Hint: Consider dividing the change over time post-initial period and applying accordingly using estimates from the equation.
