Application of BP Neural Network Model in Water Quality Simulation of Moshui River Based on Simulink

BP network model was built based on Simulink to simulate the water quality of Moshui River, Shandong, China. After verification, the model was adopted to predict the water quality of this river. The results showed that Moshui River contributed little to change of Jiaozhou Bay water quality when the emission concentration of pollutants at the estuary was lower than the predicted value.
