25.4. Role in Hydrological Modelling

Try these first

1. 1.

   Define depression storage in your own words.

   Hint

   Think about where water collects on terrain.

2. 2.

   Name one hydrological model that incorporates depression storage.

   Hint

   Recall the models we discussed regarding hydrology.

3. 3.

   What is depression storage?

   • Water that runs off immediately
   • Water held in surface features
   • Water evaporating from soil

   Hint

   Think of puddles and small dips in the ground.

4. 4.

   True or False: HRUs are used to describe uniform land areas.

   • True
   • False

   Hint

   Consider the diversity in land use within a watershed.

5. 5.

   Consider a watershed of mixed land use. Design a strategy to measure and improve depression storage based on typical HRUs present.

   Hint

   Think of different land uses and their characteristics.

6. 6.

   Evaluate the impact of urbanization on depression storage in a given region. Discuss potential measures to mitigate adverse effects.

   Hint

   Consider sustainable urban design practices.
