30.2.5. Precipitation Characteristics

Try these first

1. 1.

   What is rainfall intensity?

   Hint

   Think about how quickly the rain is falling.

2. 2.

   How does longer duration rainfall affect soil?

   Hint

   Consider time and moisture content.

3. 3.

   What does high rainfall intensity lead to?

   • Increased infiltration
   • Increased runoff
   • Less water absorption

   Hint

   Think about heavy rain events.

4. 4.

   True or False: Longer durations of rainfall always increase infiltration capacity.

   • True
   • False

   Hint

   Consider the effect of saturation.

5. 5.

   Evaluate how changes in land use from forest to urban might affect precipitation characteristics and consequently, infiltration rates. Develop a management strategy.

   Hint

   Think about the impacts of surfaces and vegetation change.

6. 6.

   Create a model predicting soil infiltration rates based on varying rainfall intensity and duration. Include variables such as soil type.

   Hint

   Consider equations you've learned related to infiltration.
