摘要：

The study aims to develop a foundation for determining when a depth-averaged two-dimensional model is sufficient for simulating hydrodynamic processes in shallow water bodies, such as the Sea of Azov, and when a three-dimensional model is advisable to achieve satisfactory results. It is shown that certain combinations of relatively high velocities (u > 1 m/s) and water depths (d > 50m) can lead to significant differences between results obtained with two-dimensional and three-dimensional models. The findings are validated by numerical modeling of steady and unsteady periodic flows in a schematic rectangular basin. The results obtained with the three-dimensional and two-dimensional models are compared, with both cases showing agreement with analytical solutions.
