25.2.4. Rainfall Intensity and Duration

Try these first

1. 1.

   What is depression storage?

   Hint

   Think about puddles and how they form after rain.

2. 2.

   How does low rainfall intensity affect runoff?

   Hint

   Consider a gentle rain and what it does to the ground.

3. 3.

   How does high-intensity rainfall affect depression storage?

   • Increases storage capacity
   • Overwhelms and causes runoff
   • No effect

   Hint

   Consider what happens when the rain is too heavy for the ground.

4. 4.

   True or False: Low rainfall intensity can allow for complete absorption of water in depressions.

   • True
   • False

   Hint

   Think about light rain versus heavy rain.

5. 5.

   Given a rainfall intensity of 50 mm/hr over a duration of one hour, discuss the potential for runoff if the site has a depression storage capacity of 40 mm.

   Hint

   Think about how much water can be absorbed before overflowing.

6. 6.

   Analyze the impact of changing climate patterns on rainfall duration and intensity. Propose a water management strategy for a region expected to see more intense storms.

   Hint

   Consider how communities can hold onto more water during heavy rains.
