27.6.3. W❑ min-Index

Try these first

1. 1.

   Define the W-index.

   Hint

   Think about how rainfall relates to runoff.

2. 2.

   What does the W❑ min-Index indicate?

   Hint

   Consider conditions when soil is full of water.

3. 3.

   What does the W❑ min-Index represent?

   • Maximum W-index value
   • Minimum W-index value during saturation
   • Constant W-index

   Hint

   Focus on the meaning of minimum in the context.

4. 4.

   True or False: The W-index is only relevant during dry conditions.

   • True
   • False

   Hint

   Think of how rain impacts water management.

5. 5.

   In a simulation, a rainfall event produced 200 mm of rain and 50 mm of runoff over 15 hours. Calculate the W-index and interpret the W❑ min-Index during conditions where soil was saturated.

   Hint

   Consider the relationship between rainfall, runoff, and time.

6. 6.

   If the W-indices collected over a season varied widely, causing estimation errors in runoff models, how might one stabilize predictions using the W❑ min-Index?

   Hint

   Focus on adjusting models for consistency based on conditions.
