Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the assumption about rainfall distribution in Theissen's method?

💡 Hint: Think about how we assume rainfall behaves within a defined area.

Question 2

Easy

What does 'adequate coverage' refer to in the context of rain gauges?

💡 Hint: Consider how data collection from different areas affects accuracy.

Interactive Quizzes

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

Question 1

What does the assumption of uniform rainfall distribution imply?

  • Rainfall is varied across the area
  • Rainfall is the same within the polygon
  • Rainfall is only measured at the stations

💡 Hint: Think about how rain gauges represent larger areas.

Question 2

True or False: Theissen's method considers topographic influences on rainfall distribution.

  • True
  • False

💡 Hint: What do we know about how mountains can disrupt rain?

Challenge Problems

Push your limits with challenges.

Question 1

Evaluate a catchment where only two rain gauge stations are placed far apart. Discuss the potential error in estimating average rainfall using the Theissen Polygon Method.

💡 Hint: Consider what the average would look like between the two stations.

Question 2

Given a scenario where mountainous terrain affects rain distribution, suggest alternative methods or adjustments to the Theissen method to improve rainfall estimation.

💡 Hint: What methods or data sources can you think of that consider elevation?
