2 cards from this section. Quick, good the night before a test.
What does the Theissen Polygon Method primarily estimate?
Think about the purpose of the method.
Is the Isohyetal Method quick to compute?
Consider the complexity involved in this method.
Which method provides a more accurate rainfall estimation?
Think of how each method represents rainfall variation.
True or False: The Theissen Method can account for topography.
Consider the assumptions each method makes about rainfall.
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.
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.
Evaluate the advantages of density versus geographical influences on rainfall.
