What is the main advantage of using the Theissen Polygon Method?
Think about how straightforward the method is.
In what type of catchment is the Theissen Polygon Method most useful?
Consider the size of areas where uniformity is more likely.
Which of the following is NOT a merit of the Theissen Polygon Method?
Think about what factors influence accuracy.
True or False: The Theissen Polygon Method is best utilized in large catchments.
Reflect on the definition of small and medium catchments.
A catchment area has five rain gauge observations at 8 mm, 10 mm, 12 mm, 14 mm, and 16 mm, covering respective areas of 1 km², 2 km², 3 km², 4 km², and 5 km². Calculate the area-weighted average rainfall.
