is the calculation of design rainfall, with a return period of 2, 5 10, 25 and 50 years and flood discharge
Haspers method. The results of the analysis showed that the design rainfall value for the 2-year return
period was 59.178 mm, 5-year return period 80.49 mm, 10-year return period 93.782 mm, 25-year return
period 109.754 mm, and 50-year return period 121.164 mm. The analysis results obtained using the
