Title in English

IMPROVING THE REGULATION OF SOIL WATER REGIME BY INNOVATIVE DRAINAGE-MODULAR SYSTEMS. CALCULATION OF DISTANCES BETWEEN REGULATING DRAINS ARRANGED AT DIFFERENT LEVELS

English abstract

The article considers water regulation by means of drainage-modular systems with different levels connecting regulating drains on drained lands, schemes of their design parameters are given. The research results and methods for calculating the parameters of these systems are presented. A new solution to the scientific and technical problem is substantiated, which consists in improving the design and improving the technology of water regulation of drained lands based on a combination of self-regulation and accumulation of water by installing a drainage-modular system with different levels of connection of hydraulically coupled drains regulating. Design and technical and technological parameters of such drainage-modular systems (regime of groundwater levels, depth of drainage, distance between them, drainage flow modules, moisture accumulation), their interaction and impact on the effectiveness of water regulation have been theoretically substantiated theoretically and investigated in laboratory and field conditions. The regularities of the formation of drainage flow and water regime of soils depending on the parameters of the drainage-modular system are investigated. It is established that the required intensity of drainage during sowing and during floods can be provided by a drainage-modular system with hydraulically connected regulating drains, while an important condition for designing a drainage-modular system is that hydraulically connected regulating drains located nearby should be laid. at different depths, which ensures the best efficiency of their work. It has been established that, compared with traditional irrigation and drainage systems, drainage-modular systems during the growing season, with an increase in the difference between drains, accumulate groundwater within deep and shallow drains. The generally accepted methods and mathematical models that describe the movement of water in the soil to calculate the basic parameters (depth of laying, distance and difference between drains) of the drainage-modular system with different levels of hydraulically connected regulating drains have been improved. Improved technology for the construction of drainage and modular systems with hydraulically connected different levels of control drains, which can significantly accelerate the pace of construction of the regulatory network, reduce the complexity of work and construction costs. It is shown that this development is the best in terms of technological and environmental, economic efficiency and investment attractive.
