Abstract

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.

2019年特大洪水期间伊亚河的洪峰流量估算

摘要

考虑了考虑到2019年城镇特大降雨洪水（导致图伦（伊尔库茨克州）发生灾难性洪水）的伊亚河峰值流量特征的方法学方法和结果。提出了一种考虑水力结构影响的水动力模型，以确定峰值流量并计算洪水位。高峰流量的特征可通过各种方法来确定，包括那些每年考虑多次洪水的方法。建议通过概括几种水文计算方法的结果来获得设计值。
