目前水质模型软件较多、如EFDC模型、MIKE模型、QUAL2K模型等

At present, there are many water quality model software, such as EFDC model, MIKE model, QUAL2K model, etc. [24, 25], but the material exchange at the water-soil interface is a very complicated process, and the material exchange at the water-soil interface also has a greater impact on water quality. The model's simulation of sediment release items is too simple, and cannot fully reflect the actual migration and transformation of pollutants in the river course, which will inevitably cause certain errors in the model simulation results
