True or False: The Isohyetal Method provides a visual representation of rainfall.
Consider whether visual representation is involved in the Isohyetal Method.
Given three rain gauges measuring 50 mm, 70 mm, and 90 mm, calculate the areal rainfall using the Arithmetic Mean Method and discuss its limitations.
Calculate the average rainfall from the gauges and think about what is not captured.
Using the Thiessen Polygon Method, describe how you would set up regions for five gauges located at coordinates reflecting their spatial distribution.
Visualize the locations of gauges and how far their influence extends.
