Annotatsiya

To date, extensive field observations and laboratory experiments on the formation and movement of bedforms in channels with alluvial beds have been conducted in various scientific centers worldwide. These studies have yielded a large volume of experimental data. Although some researchers have attempted to generalize these data and present them as unified computational relationships, fully reliable and universal results on this issue have not yet been obtained. Analysis of the existing scientific literature shows that the problem of bedform movement in channels with alluvial beds remains one of the most complex and relevant challenges in open channel hydraulics. The results of analyzing the obtained experimental data and observations indicate that changes in wave parameters directly affect the geometric and kinematic characteristics of the bedforms. In particular, it has been observed that bedforms formed under the influence of wind waves have larger dimensions compared to those formed in steady-state channel flow. This is primarily attributed to the increase in shear stresses occurring at the channel bottom as a result of wave action. The increase in these stresses leads to the enlargement of bedform parameters. Based on the theory of bedform sediment transport in open channels, methods for calculating sediment transport in channels under steady and unsteady flow conditions have been improved. This approach allows for a more accurate description of the complex morphodynamic processes occurring at the channel bottom and enhances the reliability of the calculated results.
