Abstract

<p>The relevance of addressing the problem of monitoring and forecasting&nbsp;channel processes lies in the fact that theoretical studies have not yet been&nbsp;completed and require further development by integrating the hydraulic theory&nbsp;of flows with the study of morphological features. This is especially true for&nbsp;the Amudarya, which is one of the most turbid rivers in the world: year after&nbsp;year, the riverbed becomes increasingly silted and elevated, leading to channel&nbsp;deformation and negatively affecting the stable operation of hydraulic structures&nbsp;<br /> located in the riverbed. This article investigates channel processes in the middle&nbsp;course of the Amudarya using remote sensing data. For riverbed mapping, the&nbsp;Google Earth Engine platform and Landsat satellite imagery were employed. The&nbsp;dynamics of channel changes in the water intake zone from the Amudarya to the&nbsp;<br /> Amu-Bukhara Machine Canal were analyzed. Long-term volumes of water intake&nbsp;from the Amudarya to the Amu-Bukhara Machine Canal were also studied. Based&nbsp;on the analysis of data over the past three years, it was found that the maximum&nbsp;water intake occurred in June 2025. In the water intake zone of the Amu-Bukhara&nbsp;<br /> Machine Canal, studies of riverbed relief and morphology were carried out across&nbsp;selected cross-sections. The analysis revealed that deformations of the riverbed&nbsp;in terms of depth and width occur rather rapidly. In the middle course of the&nbsp;Amudarya, the flow velocity during bank erosion reached up to 2 m/s, with erosion&nbsp;cycles ranging from 10 to 60 m, and depths between 5 and 10 m.</p>
