3.3.2. Design of Urban Drainage Systems

Try these first

1. 1.

   What is the Rational Method?

   Hint

   Think of 'Rational' as a systematic approach to calculations.

2. 2.

   Name one component of Sustainable Urban Drainage Systems.

   Hint

   Focus on infrastructure that manages stormwater.

3. 3.

   What method is commonly used to estimate peak discharge in urban drainage design?

   • Hydraulic Method
   • Rational Method
   • Snowmelt Method

   Hint

   Consider which method accounts for urban land conditions.

4. 4.

   True or False: Retention ponds are designed to temporarily hold stormwater.

   • True
   • False

   Hint

   Think about their long-term function.

5. 5.

   Design a simple urban drainage system for a small park that includes at least one type of pond. Include calculations for peak discharge assuming a storm event.

   Hint

   Use the Rational Method for your peak discharge calculation.

6. 6.

   Assess the potenital benefits of using permeable pavements in a parking lot versus traditional asphalt. Discuss environmental impacts, costs, and long-term benefits.

   Hint

   Think about the upfront costs versus potential savings over time.
