Two-section gate-regulator devices for controlling drainage flow and groundwater level

Abstract

This utility model relates to agricultural hydraulic engineering and is designed to control drainage flow and groundwater levels in irrigation systems. The sluice-regulator device has two sections, dividing the flow into a transit section and a desalination section. The desalination section is equipped with a filter-sorption layer to reduce mineralization and a water storage chamber for subsequent use, while the transit section is equipped with a regulating valve to create a backwater. The design raises the groundwater level to 0.6-0.8 m during the growing season and lowers it to a depth of at least 1.0 m during the non-growing season. The device is equipped with a catastrophic spillway. The technical result is an increase in water supply to irrigated lands using subirrigation, a reduction in drainage water salinity, and improved recycling efficiency.
