The destruction of groundwater dams, as a result of which a breakthrough flood occurs, refers to dangerous hydrological phenomena as material damage and human casualties. Due to the suddenness and transience of the dam destruction process, data on these phenomena are fragmentary and few in number, therefore it is necessary during of their study to use methods of physical and mathematical modeling. In this article, the process of destruction of an underground dam is considered, the cause of which is the overflow of water over the ridge, as a result of overflow of the reservoir. The orginality of research lies in the fact that, based on the research, the methodology proposed for determining the parameters of the breakthrough wave, as well as constructing a hydrograph of discharge costs, was confirmed.
