The average annual rainfall af gauges 1, 2, 3, and 4 are 700mm, 725mm, 750mm, and 850mm respectively. At a given month, gauges 1, 2, and 3 recorded monthly rainfall as 39mm, 43mm, and 47mm respectively. Gauge #4 was broken at that month. a) Estimate the missing monthly precipitation at gauge #4 b) Estimate the average annual rainfall over the catchment area by Arithmetical-Mean method given the area of the catchment equals 27 kan", c) If the average annual runoff from the marked area is 0.3 m/s, estimate the annual evapo- transpiration in (mm) assuming steady state conditions and assuming no exchange with the groundwater
