Abstract
The article evaluates the hydraulic processes in the collectors which constructed in irrigated fields. Illuminated the washing processes under the influence of the flow velocity in the collector bed. In order to study the washing processes in the collector basin, are covered the results of research conducted in the self-washing collector in natural field conditions. Collector 2-K-4 in Khavas district of Syrdarya region was selected as the object of research. Given cases of changes in the project parameters as a result of washing processes in the core of the collector. Were selected 5 sections in the collector and hydraulic parameters were studied. was evaluated the effect of hydraulic processes on the collector core. The studied sections show cases of change of design parameters under the influence of hydraulic processes. Soil samples were taken from the reservoir and the mechanical composition was determined under laboratory conditions. Based on the laboratory and natural field conditions results, a special graph was developed for the design of collectors on the basis of non-washable speed.
Highlights
It is known that the role of collectors in improving the reclamation of arable land is of particular importance
It is common in practice that turbid particles formed as a result of leaching processes in the collector bed can accumulate in the collector bed, in water intake sources [1,2]
Analysis of the literature showed that the issues of ensuring the static and dynamic stability of irrigation canals during operation have been extensively studied by research scientists, and have been achieved certain positive results
Summary
It is known that the role of collectors in improving the reclamation of arable land is of particular importance. The PC-13 section of this collector has a projection with water consumption Q = 800 l/s, the width of the bottom is b = 3.5 m, the depth of the stream is h = 0.30 m, the average flow velocity θ = 0.72 m/s were designed and commissioned.
