METHOD FOR RIVER FLOW REGULATION TO PROVIDE FLOOD CONTROL Russian patent published in 2007 - IPC E02B3/02 

FIELD: hydraulic engineering, particularly stream regulation to prevent territory flooding during spring tide.

SUBSTANCE: method involves creating temporary storage ponds by installing tube-type heat-exchangers in transversal stations of river bed confluent with main river bed; hermetically connecting heat-exchangers with vent risers having different heights and communicated with atmosphere, wherein the vent risers are arranged in opposite river banks; providing active circulation of air having temperature below 0°C through heat-exchangers in season preceding spring tide; creating artificial ice dams due to water freezing at heat-exchanger sections; regulating ice dam thawing regime in spring period by heat-exchanger venting rate increase or decrease; accumulating water in temporary storage ponds in spring period to extend spring tide period and to smooth flood peak.

EFFECT: prevention of flooding of territories located in central and lower main river zones during spring tide periods, decreased ecological hazard due to elimination of territory alienation and decreased time of hydrological regime and fish living condition change.
