Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the theoretical maximum rainfall represented by P₀?

💡 Hint: Think about rainfall at a single point without considering area.

Question 2

Easy

What does the decay constant 'k' indicate?

💡 Hint: Think about how rainfall spreads out over larger areas.

Question 1

What does P₀ represent in DAD relationships?

  • Average rainfall over an area
  • Maximum point rainfall at zero area
  • Decay constant

💡 Hint: Consider what maximum rainfall means in the absence of area.

Question 2

True or False: The decay constant 'k' indicates higher rainfall depth with larger areas.

  • True
  • False

💡 Hint: Think about how rainfall spreads across larger spaces.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a region with a total area of 50 km². If the maximum point rainfall (P₀) is 80 mm and the decay constant (k) is 0.05, calculate the average precipitation using the empirical formula.

💡 Hint: Make sure to apply the decay formula correctly with the given values.

Question 2

Discuss the impact of using an incorrect decay constant in flood estimation in the context of DAD relations.

💡 Hint: Think about how a higher or lower value of k might affect rainfall predictions.
