What is the first step in the Theissen Polygon Method?
Think about starting with a clear map.
What do we draw to define area boundaries around each rain gauge?
What helps create equal areas around each station?
What is the first step in the Theissen Polygon Method?
It's about starting with a clear visual.
True or False: The Theissen Polygon Method considers topography.
Think about how this simplicity could impact accuracy.
Given five rain gauge stations located at these coordinates: (0,0), (4,0), (0,3), (4,3), and (2,1.5), construct the Theissen polygons and determine their areas.
Start by plotting on graph paper for a clearer view.
A catchment area has three rain gauges with areas A1=6 km² (P1=80mm), A2=4 km² (P2=120mm), and A3=2 km² (P3=200mm). Calculate the weighted average rainfall.
Break down the computation step by step to avoid mistakes.
