3.3. Urban Hydrology

Try these first

1. 1.

   What happens to infiltration when urban surfaces become impervious?

   Hint

   Think about how rainwater interacts with hard surfaces.

2. 2.

   What is a detention pond?

   Hint

   Consider their role in flood management.

3. 3.

   What is the primary change in hydrology due to urbanization?

   • Increased infiltration
   • Reduced runoff
   • Increased surface runoff

   Hint

   Think of how water behaves on hard surfaces.

4. 4.

   True or False: Rainwater harvesting can help reduce the demand for municipal water supply.

   • True
   • False

   Hint

   Consider the benefits of using natural resources.

5. 5.

   Design an urban drainage strategy for a hypothetical city with heavy rainfall and high population density. Consider SUDS elements and how to integrate them effectively.

   Hint

   Think about how to balance nature with urban living.

6. 6.

   Evaluate the impact of urbanization on local water ecosystems. How would you propose to reverse these effects?

   Hint

   What natural features can help combat urban runoff?
