A catchment area is presented in the Figure 1. Six rainfall gauges A, B, C, D, E and F are spread over this watershed and nearby. The inter isohyets areas I, II, II, IV and V are given as 20, 50, 70, 90, and 10 km? respectively. All the rainfall and isohyets are given in cm. Estimate the mean precipitation over this catchment area using arithmetic mean and isohyetal methods.
