Try these first

1. 1.

   Define rainfall intensity.

   Hint

   What unit is used to express rainfall intensity?

2. 2.

   What can high rainfall intensity (>50 mm/hr) lead to?

   Hint

   Think about what happens in cities during heavy rains.

3. 3.

   What is rainfall intensity measured in?

   • Liters per minute
   • Millimeters per hour
   • Cubic meters per second

   Hint

   Think about both volume and flow rate.

6. 6.

   Explore the historical data for rainfall intensity in your city. What trends do you observe, and how should this inform local urban planning?
