Zusammenfassung:	Methodological approaches and results of estimation of peak flow characteristics of the Iya River taking into account the extreme rainfall flood in the town of 2019, that led to the catastrophic flood in Tulun (the Irkutsk region), are considered. A hydrodynamic model considering the impact of hydraulic structures is proposed to determine the peak flow and to calculate flooding levels. The characteristics of peak flow are determined by various methods, including those considering several floods per year. It is recommended to obtain design values by generalizing the results of several methods of hydrological calculations.
