Abstract

Purpose. The choice of a scientifically and technically substantiated method for integrating the equations of unsteady gradually changing flow movement in an open channel in highland conditions when a dam breaks.

Methods. Approximate integration methods for differential equations.

Findings. The use of the finite-difference method for integrating differential equations (method of characteristic equations of S.A. Khristianovich) is proposed for unsteady gradually changing flow in highland conditions when a dam breaks.

Application field of research. The proposed solution of the equations of unsteady gradually changing movement in highland conditions when breaking dams can be used to solve practical problems in determining the main parameters of the displacement wave and the zones of harmful effects on the territory adjacent to the high mountains.
