“…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.

“…As already mentioned above, there has recently been a sharp change in the hydrological regime of the river. There are intense deformations of the supply channel border since it runs on easily washed-out soils [19][20][21][22][23][24][25][26][27][28][29].…”

Irrigation sedimentation tanks in the bed of the pumping station inlet channels

The article analyzes the dynamics of channel processes in the irrigation pumping station inlet channels. The field studies of hydraulic and alluvial sediment regimes in the supply channels of pumping stations are analyzed and summarized. The studies of supply channel water flow under conditions of extremely high turbidity of the flow and variability of the morphometric characteristics of the channel are presented. The conditions under which the Saint-Venant equations satisfactorily describe the channel flows in the bed of the supply channels are given. Saint-Venant's twodimensional equations were numerically implemented using an explicit finite-difference scheme. In addition, the results of calculations of the flow field in the supply channels are presented. According to the results of numerical studies, the width of the sedimentation tank was taken to be equal to the design width of the channel, and the speed of water flow in it was 0.25 m/s. The length of the sedimentation tank, ensuring the retention of sediments of the finest fraction (0.05 mm in diameter), was 1042 m. The siltation time of the sedimentation tank can be reduced by 15…20% and amount to about 15 months, considering the unevenness of the velocity distribution diagram in the horizontal plane and the trapezoidal crosssection of the clarifier. Nevertheless, the arrangement of two parallel chambers of the sedimentation tanks makes it possible to be stable for a sufficiently long time.
