Question 1.
What is an empirical infiltration model?
Show hintHide hint
Think about whether the model is based on experimentation or theory.
Question 2.
What does Horton’s model assume about infiltration capacity?
Show hintHide hint
Focus on the term 'exponentially' regarding time.
3Question 3.
What does Horton’s model predict regarding infiltration?
- Infiltration increases over time.
- Infiltration decreases over time.
- Infiltration remains constant.
Show hintHide hint
Consider the effects over time.
4Question 4.
True or False: Philip’s Equation is only applicable to long-duration rain events.
- True
- False
Show hintHide hint
Think about the timing of infiltration.
Question 5.
Using Horton’s infiltration model, determine the infiltration rate at time t=5 minutes if the initial infiltration rate is 20 cm/h, the final rate is 10 cm/h, and the decay constant is 0.1.
Show hintHide hint
First, calculate the exponent before multiplying.
Question 6.
Compare and contrast the applications of Philip’s equation and Green-Ampt model in urban vs. agricultural settings.
Show hintHide hint
Think about the physical environment and the types of surfaces involved.
