27. Infiltration Capacity

Try these first

1. 1.

   What is infiltration?

   Hint

   Think about where rainwater goes after hitting the ground.

2. 2.

   Name one factor that affects infiltration capacity.

   Hint

   Consider how different types of soil feel.

3. 3.

   What does infiltration capacity represent?

   • Maximum water absorption rate
   • Soil temperature
   • Air moisture content

   Hint

   It's a key concept in hydrology.

4. 4.

   True or False: Clayey soils generally have higher infiltration rates than sandy soils.

   • True
   • False

   Hint

   Consider how each type of soil feels when wet.

5. 5.

   Design an experiment using an infiltrometer to measure the infiltration rate of two soil types (sandy and clay). Discuss the expected outcomes and methodology.

   Hint

   Consider soil preparation and weather conditions before the experiment.

6. 6.

   Apply Horton's Equation to predict infiltration for a given rainfall. If f₀ = 50 mm/hr, fc = 10 mm/hr, and k = 0.1, find f(t) after 1 hour.

   Hint

   Remember how to handle exponentials in calculations.
