Hello, in this question the average rainfall need to be calculated by the use of Thiessen polygons.
Q3: In a catchment area, approximated by a rectangular of coordinates (50, 0), (100, 50), (50, 100), and (0, 50) km, four rainfall stations are situated inside the catchment. The coordinates of the stations and the annual precipitation recorded by the four stations in 2020 are given in Table below. Determine the average annual precipitation on the catchment using Thiessen-polygon method. Station Coordinate Precipitation (cm) 1 (50, 75) 85 2 (75, 50) 135 3 (50, 25) 95 4 (25, 50) 140
