24.5.3. Stemflow (Sf)

Try these first

1. 1.

   What does stemflow refer to?

   Hint

   Think about how water travels after it hits the tree.

2. 2.

   Name a factor that can influence stemflow.

   Hint

   Consider what type of plants are involved.

3. 3.

   What is stemflow?

   • Water that flows from leaves
   • Water flowing down stems
   • Water soaking into soil

   Hint

   Focus on where the water goes after the rain hits.

4. 4.

   True or False: Stemflow increases soil moisture near plant bases.

   • True
   • False

   Hint

   Think about how the water interacts with the ground!

5. 5.

   Considering a forest ecosystem with a total precipitation of 1000 mm/year, where 30% is intercepted as stemflow. Calculate the volume of water that contributes to stemflow and its potential effect on soil moisture.

   Hint

   Use the percentage to calculate the volume based on the total precipitation.

6. 6.

   Discuss the potential implications of decreased stemflow due to urban development on local groundwater levels.

   Hint

   Consider how urban surfaces affect water flow.
