Question

There are 10 rain gauge stations available to calculate the rainfall characteristics of a catchment whose shape can be approximately described by straight lines joining the following coordinates (Distances in kilometers): (30.0) (80,10), (110,30), (140,90), (130,115), (40, recorded in them in the year 1981 are given below. Determine the average rainfall ver the catchment by Theissen Polygon method and Arithmetic Mean method 110)/(15,60). Coordinates of the rain gauge stations and the annual rainfall Station Coordinates (km) Rainfall (cm) (0,40) (50,0) (140,30) (140,80) (90,140) 132 136 93 81 85 124 156 128 6(0.80) (40,50) (90,30) (90,90) (40,80) 860.041102 10 128
