32.2.B. Physiographic Factors

Try these first

1. 1.

   What does topography refer to?

   Hint

   Think about how land shapes affect water flow.

2. 2.

   Name one effect of vegetation on runoff.

   Hint

   Consider how plants interact with rainfall.

3. 3.

   Which factor increases surface runoff?

   • Dense vegetation
   • Clay soil
   • Sandy soil

   Hint

   Consider which soil holds water better.

4. 4.

   True or False: Urbanization decreases runoff.

   • True
   • False

   Hint

   Think about what happens when more concrete is added.

5. 5.

   Consider an area with a diverse topography of steep and flat lands. Predict how a sudden storm would affect runoff distribution across the landscape. What strategies would you propose to manage the impacts?

   Hint

   Think about how water travels and where it accumulates.

6. 6.

   Design a theoretical urban landscape incorporating vegetation to reduce runoff. What key elements would you suggest, and why?

   Hint

   Consider areas where water can be absorbed before hitting the ground.
