Title in English

WATER REGULATION OF DRAINAGE-MODULAR SYSTEMS ON DRYED LAND

English abstract

The article discusses water regulation by drainage-modular systems with different levels connecting control drains on drained lands, shows the diagrams of their design parameters. 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 control drains. 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 has been established that the necessary drainage intensity during the sowing period 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 that are arranged side by side must be laid on different the depths which ensures the best efficiency of their work under different modes of ground feeding, while deep drainage is more effective when connected to shallow and deep collectors at the same time. It has been established that, compared with traditional irrigation and drainage systems, drainagemodular 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 have been improved that describe the movement of water in the ground for calculating the main parameters (laying depth, distance and difference between drains) of VHI with different level hydraulically connected regulating drains. The technology for the construction of VHI with hydraulically coupled different levels of regulating drains has been improved, which can significantly accelerate the pace of the construction of the regulatory network, reduce the complexity of work and the cost of construction. It is shown that this development in terms of technological and environmental efficiency occupies an intermediate place between traditional preventive and humidification locks and is the best in terms of economic efficiency and investment attractiveness.
