A rainfall excess of 2.1 cm in 1 hour produced a triangular runoff hydrograph with a peak of 20 m3/s at 2 hours and a return to zero at 10 hours. According to the UH theory, the runoff hydrograph for rainfall excess of 4.2 cm in the same time period Cannot be determined since the unit is not 1 cm would have a peak of 40 m3/s at 4 hours would have a peak of 40 m3/s and a total runoff period of 20 hours would have a total volume of 720 000 m3 and a peak of 40 m3/s
