CONTROL METHOD FOR WATER WITHDRAWAL REGIME AND WATER-INTAKE FACILITY FOR CONTROL METHOD IMPLEMENTATION

FIELD: hydraulic structures, particularly fish passes in water-intake structures. ^ SUBSTANCE: method involves supplying water stream free of young fish in waterway; forming hydraulic screen near water-intake influence area to separate above area from main stream of water-intake structure; forming whirlpool area near water-intake shore edge. Water stream is formed upstream water-intake structure. Water for users is taken from whirlpool area formed by inner water spray boundary and shore edge. Facility includes water-intake structure arranged at shore line, water-intake pipes connected with pump, stream former and means for water stream creation in waterway. Means for water stream creation is made as channel operating in non-pressure regime and having outlet part arranged upstream water inlet. Marks formed on channel bottom and waterway bottom coincide one with another. Stream former is located downstream water intake and directed in downstream direction. ^ EFFECT: creating of hydraulic conditions to protect young fish from ingress in water-intake structure. ^ 14 cl, 9 dwg
