Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What assumption does the Theissen method make about rainfall distribution?

  • Uniform across polygons
  • Concentrated near gauges
  • Varying with elevation

💡 Hint: Consider how rainfall is treated within the areas defined.

Question 2

True or False: The Theissen Polygon Method takes topography into account.

  • True
  • False

💡 Hint: Think about how elevation changes could affect rainfall.

Challenge Problems

Push your limits with challenges.

Question 1

Given the coordinates and rainfall measurements for four rain gauges in a rectangular catchment, determine the area-weighted average rainfall using the Theissen Method's steps.

💡 Hint: Remember to visualize the area each gauge covers.

Question 2

In a mountainous catchment area, you have the choice to use either the Theissen Method or the Isohyetal Method. Discuss the implications of choosing one over the other based on your observations.

💡 Hint: Consider the terrain and environmental influence on rainfall.
