“…A characteristic feature of this study is that during the studies, it was ensured that the connection of the pounds in the appearance of the hydraulic jump is formed not by adjustment by the lower pound but by the actual operating conditions of the structure. In this case, the direction of research was determined mainly by the dynamics of the Froude number and the kinetic parameters of the flow, the dynamics of the calculated consumption, the calculated relative magnitudes of the structural elements [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39].…”

For multi-section drainage facilities, it is important to develop operational measures based on maneuvering moving barriers. Maneuvering of moving barriers is a measure that carries out the flow of water from the upper reaches to the lower reaches at the required level, taking into accounts the design features and operational mode of the hydraulic regime of the drainage structure. The maneuvering mode in the flow of water from the discharge structures ensures the order of opening, phasing, and level of opening of these movable barriers. Hydraulic conditions are associated with the effective control of the hydraulic regime in the lower part of the drainage structure or the suppression of excess kinetic energy, the reversal of the flow, or the prevention of post-riser deformation processes. Creating conditions ensuring that the hydrotechnical and hydropower construction of the water transfer or discharge facility is adapted for use in conjunction with a hydropower plant, water intake, sluices, and flow control system.

“…The B/H value was 26-63 in the area above the water intakes and 63-77 in the area below the water intake. The value of the surface water flow velocity in the area above the water intake changed from 0.78 to 1.08 m/s, below the water intake -from 0.5 to 0.75 m/s [17][18][19][20][21][22][23][24][25][26]. The optimal route and boundaries of the location of the pioneer ditch are assigned depending on the location of the main stream of the river relative to the point of the damless water intake.…”

The paper presents the results of field research in the area of the damless water intake of the KMC on the Amudarya River. The article developed the optimal route and boundaries of the pioneer digging location, depending on the area of the main stream of the river relative to the point of the damless intake. It also provides hydraulic calculations for improving the condition of a damless water intake and recommendations for the rational use and placement of a dredgers fleet when laying a route of a ditch and cleaning it.

“…Clearance of the flood reservoir from muddy sediments should be considered based on calculations. It is necessary to calculate the current profit from the flood reservoir and consider the targeted use of the flood reservoir in the future, taking into account the loss of useful volume [20][21][22][23][24][25][26][27][28].…”

Results and analysis of field research in flood reservoirs in Kashkadarya region

et al. 2021

View full text Add to dashboard Cite

The article presents field research conducted in Langar, Dehkanabad, Shurabsoy flood reservoirs in the Kashkadarya region. Many problems result from floods in the reservoirs; there are disturbances in the discharge and drainage facilities during the passage of accidental floods. At the same time, there was a large accumulation of turbid sediments in flood reservoirs. In the article, the calculations using empirical formulas for predicting the number of turbid sediments in Langar, Dehkanabad, Shurabsoy flood reservoirs up to 2025-2030 years are also presented, and it is noted that at present, their useless volumes are full of turbid sediments. Preliminary recommendations for assessing the safety of flood reservoirs have been developed.
