Challenge Problems

Push your limits with challenges.

Question 1

If the average temperature last month was 30°C and Ra was 20 MJ/m²/day, calculate the ET using the Hargreaves Method. Discuss how changes in Ra would affect the result.

💡 Hint: Revisit how the components affect evapotranspiration calculations.

Question 2

Compare the results of using the Hargreaves Method versus the Thornthwaite Method when given the same climatic data. What factors might lead to difference in outputs?

💡 Hint: Recall how each method uses different parameters for its calculations.
