本文通过室内矩形水槽装置设置了8组流速从0-1m/s的水动力试验，模拟

In this paper, 8 sets of hydrodynamic tests with flow velocity ranging from 0-1m/s were set up through the indoor rectangular water tank device to simulate the starting law of river sediments under different hydrodynamics, determine the concentration of heavy metals in water at different flow rates, and establish the The expression of the relationship between the release flux of heavy metal indicators and the flow rate, and then the results were applied to field experiments. The results showed that:

In this paper, 8 sets of hydrodynamic tests with flow rate from 0-1m/s are set up by the indoor rectangular sink device, the starting law of sediments in different hydrodynamic lower river channels is simulated, the concentration of water weight metals in different flow dough is determined, the relationship expression between the release flow of the various heavy metal indicators in the sediments is established, and the results are applied to the field experiments, the results are shown:

In this paper, eight groups of hydrodynamic experiments with velocity from 0-1m / s were set up in a rectangular flume. The incipient law of river sediment under different hydrodynamic forces was simulated, and the concentration of heavy metals in water at different velocities was measured. The relationship between the release flux of heavy metals in sediments and the flow velocity was established
