The 6-hour unit hydrograph of a watershed is represented by an isosceles triangle with the peak of 180 m3 s-1 and time to peak of 18 hours. The phi-index (∅) of this watershed is 3.0 mm h-1 and the constant baseflow is 20 m3 s-1. The accumulated rainfall received in this watershed at 6 h and 12 h from the start of the storm are 38 mm and 106 mm, respectively. The resulting peak of the flood hydrograph due to this storm event is
