Abstract

In the arid areas of the river itself, the direction of flow is characterized by changes depending on its hydrological regime. As a result of these changes, the flow can be branched into several streams and the flow can be distributed differently in terms of quantity. As the river passes through lightly washed soils, these streams have different depths, and its hydraulic elements and river morphometry can vary at different intensities. Changes in hydraulic resistance as a result of such changes can affect the water permeability of streams. It should be noted that, depending on the form of morphometry, the roughness of the stream and the shoreline may vary at the same constant size of depth. This could be the Karshi Main and Amu Bukhara Mashina canals, which receive the most dam-free water from the Amudarya to the irrigated areas of the Republic of Uzbekistan. In these catchment areas, rapid washing of riverbeds, uneven distribution of flow velocity, and the constant distance of the stream from the dam intake facility away from the main intake facility complicate operating conditions and reduce the amount of water required to enter the canal during the growing season.
