Question
The area shown in Fig. below is composed of a square plus an equilateral triangular plot of side 20 m. The annual precipitations at the rain-gauge stations located at the four corners and center of the square plot and apex of the triangular plot are indicated in the figure.
- Estimate the mean precipitation (cm) over the area by Thiessen polygon method.
- Estimate the mean precipitation (cm) over the area by arithmatic mean method.
- Calculate the percentage variation between these two methods considering the Thiessen polygon value as the base value.
