The disclosure discloses a test method for simulating sediment pollutant release under the effect of river channel erosion, which comprises preparing a test device, presetting a water depth and a flow velocity in a test water tank, and calculating a flow rate in the test water tank; paving the sediment in a sediment storage box, and covering an upper surface of the sediment with a water baffle; adding water into the test water tank until a preset water depth, starting a variable speed motor to drive a flow-making propeller to run to make the flow rate reach the required flow rate and keep the flow velocity constant; after the water flow becomes constant, the water baffle retracting to expose the surface of the sediment; opening sampling ports for layered sampling; measuring water; and respectively measuring concentration variation and vertical distribution features of sediment pollutant under different simulated power conditions.
