24.7.1. Reduces Surface Runoff

Try these first

1. 1.

   What is interception?

   Hint

   Think about where rainwater goes before it hits the soil.

2. 2.

   Name one component of interception.

   Hint

   This is what happens after precipitation falls on vegetation.

3. 3.

   What portion of precipitation can be intercepted by vegetation?

   • 5%-15%
   • 10%-40%
   • 45%-60%

   Hint

   Think about the role of trees in capturing rain.

4. 4.

   True or False: Interception helps reduce flooding.

   • True
   • False

   Hint

   Consider what happens to rainwater in urban areas.

5. 5.

   If a forested area receives 100 mm of rain, and 30 mm is captured by interception, how much rainfall reaches the soil?

   Hint

   Think about what interception does with the rainfall.

6. 6.

   Consider two different areas: one with a dense forest and another with a sparse grassland. If both receive the same precipitation, what differences can you expect in their surface runoff levels? Why?

   Hint

   Reflect on how trees and vegetation capture rain differently.
