Due to climate change the number of extreme weather events is increasing worldwide. Тhе amount of rainfall in the world increased Ьу 40%. Heavy rainfall often leads to flooding causing social and economic damage to the affected areas. The paper presents а mathematical model of the formation of slope runoff as а result of heavy rainfall in the river basin. А method for calculating the extreme water flow rate in the outlet section is developed based оп the Euler difference scheme for ordinary differential equations. Numerical experiments were carried out in the drainage area of the Sardoba reservoir where оп Мау 1, 2020, the dam body of the northeastern part of the dam was destroyed. The article explores the main points: heavy rainfall has more energy than ordinary rain; heavy rainfall draws soil particles into the flow, increasing the flow rate; the mathematical model of the storm runoff formation allows calculating the extreme flow in the section of the river basin; the calculation method сап Ье used in the design of reservoirs.
