LAYER-MODULAR DRYING-HUMIDIFYING POLDER SYSTEM Russian patent published in 2022 - IPC E02B11/00 A01G25/02 

FIELD: drainage and irrigation meliorations.

SUBSTANCE: invention relates to drainage and irrigation melioration and can be used to protect the reclaimed area from river flood waters and the efficient use of the system's water resources when draining and moistening reclaimed lands. The developed tiered-modular drainage-humidification polder system consists of flooded and non-flooded tiers of polders with control tanks 5, bunded by dams 6, located on the territory of the flooded polder, and involves the placement of crop rotation plots in the form of modules of two tiers. The mark of the top of the dams 6, limiting the control tanks 5 for accumulating water, located in the flooded polder, is equal to the mark of the top of the dam 17, which limits the non-flooded polder. The slope of the ground surface in the flooded polder is planned towards the non-flooded polder. The filling of the control tanks 5 is carried out by the pumping station 13 through the additional pipeline 9.

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