Challenge Problems

Push your limits with challenges.

Question 1

Given a region with varying but dense rainfall data, create a simulated condition that justifies the usage of the Isohyetal Method over Theissen. Explain your reasoning.

💡 Hint: Consider how rainfall changes in relation to elevation and surface features.

Question 2

Assuming a network of 10 rain gauges evenly spaced in a small catchment, determine the feasibility of using the Theissen Method compared to using Isohyetal if the catchment shows significant rainfall variation due to proximity to mountains.

💡 Hint: Evaluate the advantages of density versus geographical influences on rainfall.
