Challenge Problems
Push your limits with advanced challenges
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.
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.
