This article intends to simulate the law of sediment initiation through an indoor sink device, analyze the content of heavy metals in the overlying water at different flow rates, study the release law of heavy metals in sediments under dynamic water conditions, and apply the conclusions to the Le'an River in order to further reveal the heavy metals in sediment Source release law provides theoretical reference.

In this paper, it is proposed to simulate the sediment initiation law through the indoor sink device, analyze the heavy metal content in the overflow water at different flow speeds, study the release law of heavy metals in sediment under dynamic water conditions, and apply the conclusions to the Le'an River, in order to provide theoretical reference for further revealing the endometal release law of sediment heavy metals.

In this paper, the indoor flume device is used to simulate the sediment start-up law, analyze the content of heavy metals in overlying water at different velocities, and study the release law of heavy metals in sediments under dynamic water conditions, and apply the conclusion to Le'an River, so as to provide theoretical reference for further revealing the internal release law of heavy metals in sediments.
