Hydrological analysis is very important in the scientific development of water resources. In the planning and maintenance of civil structures water, the design flood discharge needs to be assessed. Tapung Kanan River and Tapung Kiri River are the upper reaches of the Siak Watershed. The distribution of rainfall around the river fits the gumbel distribution and meets the criteria in the chi square test and the Kolmogorov test. Hyetograph design rain uses the distribution of rain patterns in the Water Research Center with a duration of 3 hours. Based on the reliability of the synthetic unit hydrograph (SUH) ITB-1, the two rivers showed good performance with an average volume accuracy of 98.09% and an average volume/DRO control ratio of 1,0006. Tapung Kanan River Flood discharge for a period of 10 years obtained 6380.83 m3/sec with a runoff volume of 22,664,541.84 m3 while Tapung Kiri River Flood discharge for a period of 10 years obtained 6207.29 m3/sec with a runoff volume of 22,189,284.58 m3. © 2020 Published under licence by IOP Publishing Ltd.
