MODULAR DRYING AND HUMIDIFYING POLDER SYSTEM Russian patent published in 2023 - IPC E02B11/00 

FIELD: agricultural land reclamation.

SUBSTANCE: system comprises flooded and non-flooded polders, drains and second-order drainage headers connected to storage and transport facilities and a supply and discharge channel connected to a water intake-water source. Linear storage and transportation facilities are connected by pipelines to multifunctional wells located in the boundary zone of two levels of the process site. In the interface zone with the lower level, the wells have vertical slots from the top of the well ring to the level of the groundwater level mark corresponding to the drainage rate. The upper level of the process site corresponds to the mark of the ground surface of the adjacent area, and the lower level corresponds to the mark of the groundwater level corresponding to the drainage rate.

EFFECT: protection of the reclaimed area from flood waters, drainage of the area and moistening of agricultural crops during the dry growing season, as well as an increased reliability of the system and efficiency of using water resources.
