The article describes the progress of a hypothetical flood in a watercourse reach, including potential changes in the channel geometry. The quasi-hydrodynamic model employed takes into account changes in the temperature of the medium over time, the complex structure of the watercourse channel, almost any recharge pattern and any engineering structures in the channel. As a result, it is possible to estimate probable changes in the geometry of precisely reproduced reaches of existing watercourse channels during significant floods and include them, e.g., in real-time operational models.
