26. Infiltration

Try these first

1. 1.

   What is infiltration?

   Hint

   Think about how water soaks into soil during rain.

2. 2.

   Name one factor that affects infiltration.

   Hint

   Consider the types of soil.

3. 3.

   What is the primary function of infiltration?

   • A) To cause runoff
   • B) To allow water into the soil
   • C) To prevent erosion

   Hint

   Consider the process of water interacting with soil.

4. 4.

   True or False: Sandy soils typically have a lower infiltration rate than clay soils.

   • True
   • False

   Hint

   Think about the size of soil particles.

5. 5.

   A plot of land has different soil types: sandy, loamy, and clay. Discuss how you would design an irrigation system taking infiltration rates into account.

   Hint

   Consider how different soils retain and absorb water.

6. 6.

   Using Horton’s equation, predict the infiltration rate at time t if f_c = 10 mm/hr, f_0 = 30 mm/hr, and k = 0.1. Discuss its implications for a rainy season.

   Hint

   Use the equation f(t) = f_c + (f_0 - f_c)e^(-kt).
