Title in English

REGULATION OF THE SOILS WATER REGIME OF DRAINAGE SYSTEMS FOR THE HUMID ZONE

English abstract

The article deals with water regulation by drainage systems on drained lands, and diagrams of their design parameters are given. The results of analytical studies of regulating drains of drainage-module systems and methods of calculating their parameters during groundwater supply are given. Research has established that a drain laid at different distances from the waterproofing layer will have different hydrological properties along its length, and the specific inflow to the drain, under unchanged hydrogeological and soil conditions, will be different in different parts of its cross-section. Filtration calculations and their analysis made it possible to propose innovative drainage modular systems that provide optimal regulation of groundwater levels on drains in the humid zone, and as experimental studies have shown, are more effective in regulating groundwater levels and, at the same time, the water regime of soils. Studies have also shown that the main component parameters for calculating the distances between regulating drains of modular drainage systems are pressure and flow, and the optimal determination of these parameters depends not only on the dynamics and depth of the groundwater level in the soil, but also on the cost of installing a drainage system and, ultimately, calculation, its economic efficiency. The equations obtained theoretically and experimentally can be used to calculate when designing the distances between perfect drains of shallow and shallow-deep laying of the drainage-module system with soil water supply.
