Abstract: A laboratory-scale physical model of the sand column pore aquifer (100 cm in diameter, 100 cm in height, and 70 cm in fill height) was built and a numerical model of groundwater flow in MODFLOW was constructed based on the physical model. The feasibility of artificially controlling the groundwater flow field and hydraulic gradient through a single well pump-out-return infiltration synchronous cycle process and the influence of hydrogeological and hydrodynamic conditions were investigated. The results show that after the physical device is operated for a period of time, the water level drop depth curve no longer changes, the pumping-return seepage reaches equilibrium, and the accuracy of the calibrated numerical model based on the measured water level at different locations and depths in the sand column aquifer is satisfactory (the Nash efficiency coefficient is greater than 0.8), which can better portray the actual groundwater flow field in the physical model. The change of pumping-return seepage volume has almost no effect on the range of water level landing funnel, and the radius of influence (28.0-28.5 cm) hardly changes with the change of pumping-return seepage volume, while the change of pumping-return seepage volume has a greater effect on the depth of water level landing funnel, the greater the pumping-return seepage volume, the greater the depth of landing funnel, when the pumping-return seepage volume is 1, 2.5, 5, 10 cm³/s, the maximum depth of landing funnel reaches 1.76, 4.55, 9.75, 4.55, 9.75, 10 cm³/s, respectively. The water level at different locations of the aquifer is related to the magnitude of the withdrawal-return seepage volume and the permeability of the aquifer when hydraulic control is achieved. The linear relationship between Q/K  and h2-hw2/lgr-lgrw  (h- water level at an aquifer, h_w- water level at the pumping well, r- the distance between an aquifer and the pumping well shaft, r_w- radius of the pumping well) was determined with the fitting coefficient R² = 0.99. The physical model of the laboratory-scale sand column aquifer and the numerical model of groundwater flow were used to demonstrate the relationship between different hydrodynamic conditions and The laboratory-scale physical model of sand column aquifer and numerical model of groundwater flow are important tools to demonstrate the feasibility of single-well pumping-infiltration synchronous cycle groundwater control technology under different hydrodynamic and hydrogeological conditions and can provide important references for the application of this technology in practical sites.
