Abstract To solve the problems of harmful intake flow patterns affecting the pumping system characteristics and safe operation of pumping station,the author improved the intake flow patterns by adopting the method of modeling test with a 1∶50 model of Jingdu pumping station including the east sluice,west sluice and the diversion canals of 4 pumping stations.Based on Froude criterion,the intake flow pattern can be modeled accurately by increasing flow velocity properly.By setting a reverse "Y" guide baffle and a floor sill,the large scale swilling flow and sedimentation in diversion canal were reduced.It provides a good intake flow condition for the safe and economic operation of pumping station.pumping station;diversion canal;flow pattern;improvement;modeling test
