Abstract
The article presents the study results of changes in flow hydraulic parameters and morphometric elements of the river in the area of the main dam intake structure. A model for studying the direction of flow and other parameters of the flow in the area of the main structure for obtaining water from the Amudarya without a dam has been developed. A functional graph of the depth dependence of the expenditure on the study object was obtained. Graphs of the functional dependence of the diurnal cross-section of the riverbed on the flow depth and the variation of the flow velocity depending on the flow depth were constructed. The direction and distribution of the flow in the area of the main dam intake structure were studied.
Highlights
One of the largest rivers in Central Asia, the Amudarya, is used for irrigation without dams
In determining the solution to this problem, it is important to adjust the direction of movement of water flow in this area, to study the dynamics of the hydraulic parameters of the flow
In the non-dam intake model, the water flows from the lower bay (9) to the discharge channel (11) through the sluice (10)
Summary
One of the largest rivers in Central Asia, the Amudarya, is used for irrigation without dams. In determining the solution to this problem, it is important to adjust the direction of movement of water flow in this area, to study the dynamics of the hydraulic parameters of the flow. Due to insufficient study of the laws of flow dynamics in the upper section of the river's main dam intake structure in experimental and field studies, this direction was identified as the main goal of the scientific article.
