13.5.3. Bernard’s Equation

Try these first

1. 1.

   What does Bernard's Equation aim to estimate?

   Hint

   Consider what aspects of rainfall the equation relates to.

2. 2.

   Name two empirical constants in Bernard's Equation.

   Hint

   Think about the components of the equation.

3. 3.

   What does I represent in Bernard's Equation?

   • Rainfall Volume
   • Rainfall Intensity
   • Rainfall Duration

   Hint

   Think about what you calculate specifically in hydrology.

4. 4.

   True or False: The values of K, b, and n are constant across all geographical locations.

   • True
   • False

   Hint

   Consider the impact of local rainfall characteristics.

5. 5.

   Given an area prone to rainfall, if historical data suggests K = 70, b = 3, and n = 1.5, compute rainfall intensity for a storm duration of 45 minutes.

   Hint

   Substituting in the values will solve for I.

6. 6.

   Discuss how findings from Bernard’s Equation might change if applied to a tropical region versus a desert region.

   Hint

   Consider climatic impacts on rainfall patterns.
