25.3. Quantification of Depression Storage

Try these first

1. 1.

   What is depression storage?

   Hint

   Think about where water often collects after heavy rain.

2. 2.

   Name one method used to measure depression storage.

   Hint

   Consider a tool that measures water infiltration.

3. 3.

   What is the typical range of depression storage for forests?

   • 0-1 mm
   • 2-5 mm
   • 1-3 mm

   Hint

   Think about which land types retain the most water.

4. 4.

   True or False: Urban areas inherently have high depression storage.

   • True
   • False

   Hint

   Consider why water might not stay in cities.

5. 5.

   Given the empirical values for forests and urban areas, calculate the difference in depression storage.

   Hint

   Subtract the urban storage from that of the forest.

6. 6.

   Explain why measuring depression storage is critical when designing stormwater management systems.

   Hint

   Consider how water flow and accumulation affect system design.
