32.1. Components of Runoff

Try these first

1. 1.

   What is surface runoff?

   Hint

   Think about rain falling quickly on roads.

2. 2.

   Define base flow.

   Hint

   Remember, it's about underground sources.

3. 3.

   What is the term for the flow of water when rainfall exceeds soil absorption capacity?

   • Base Flow
   • Interflow
   • Surface Runoff

   Hint

   It's the most visible type of runoff.

4. 4.

   True or False: Base flow is the water that primarily moves quickly to streams at the onset of rain.

   • True
   • False

   Hint

   Think about groundwater contributions.

5. 5.

   Design a simple urban drainage system considering all runoff components. How would you balance surface runoff and interflow?

   Hint

   Think about landscaping and infrastructure.

6. 6.

   Analyze a region experiencing drought. How does understanding base flow inform water resource management strategies?

   Hint

   Focus on the relationship between groundwater and surface water during dry spells.
