Q. Rainfall depth over a watershed is monitored through six number of well distributed rain gauges. Gauged data are given below
| Rain Gauge Number | 1 | 2 | 3 | 4 | 5 | 6 |
| Rainfall Depth (mm) | 470 | 465 | 435 | 525 | 480 | 510 |
| Area of Thiessen Polygon (×104 m2) | 95 | 100 | 98 | 80 | 85 | 92 |
The Thiessen mean value (in mm, up to one decimal place) of the rainfall is
Ans: 478.5 – 479.5
