Determine the average annual rainfall overt the watershed. ATTACH YOUR SOLUTION: There are 10 raingauge 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 kilometres): (30, 0), (80, 10), (110, 30), (140, 90), (130, 115), (40, 110), (15, 60). Coordinates of the raingauge stations and the annual rainfall recorded in them in the year 1981 are given below. Station 1 2 3 4 5 Co-ordinates (0, 40) (50, 0) (140, 30) (140, 80) (90, 140) Annual Rainfall (cm) 132 136 93 81 85 Station 6 7 8 9. 10 Co-ordinates (0, 80) (40, 50) (90, 30) (90, 90) (40, 80) Annual Rainfall (cm) 124 156 128 102 128 A 139 cm B 130 cm C 138 cm 135 cm
