Abstract

The article focuses on increasing the efficiency of soil fertile irrigation canals. The useful coefficient of the channels depends on many factors (such as the type of soils constituting a canal, the water-carrying capacity of the canal, the hydraulic elements of the canal and the operational condition), their joint study will enable to define the actual beneficial coefficient of the channel. The article also analyzes the methods for filtering leading researchers for filtering processes in soil-leach irrigation canals and compared the computational methods presented in the regulatory documents and analyzed based on the results of the analysis. The article focuses on natural-field conditions in the study of soil-water dynamics and filtration processes in natural conditions in determining the coefficient of usefulness in soil-leach irrigation canals. At the same time, filtration processes are directly related to the change (increase or decrease) of the water level, which in some cases changes rapidly. The article has developed a graph of determination of the useful coefficient of value depending on the water level of the channel by measuring-monitoring of hydrotechnical, hydrogeological and hydrometric methods in various methods of filtration processes in soil-sprinkling irrigation canals. With the help of the developed graphs, the possibility of increasing the efficiency of the channel’s useful coefficients in soil-leach irrigation canals has been identified. The recommendations developed within the article provide a good effect on the management of water resources in irrigation canals and water conservation in meeting the water demand of consumers.
