Wang, H., 2020. Application of back propagation (BP) neural network in water quality assessment: A case study of Ashi River Basin. In: Gong, D.; Zhang, M., and Liu, R. (eds.), Advances in Coastal Research: Engineering, Industry, Economy, and Sustainable Development. Journal of Coastal Research, Special Issue No. 106, pp. 377–380.

The artificial neural network (ANN) theory and method was adopted to establish a back propagation (BP) neural network model for the assessment of water quality. Considering the water quality in the Ashi River basin as an example, a comparative analysis between the obtained results and the results from the Nemerow index method shows that the BP neural network model is applicable to evaluate the river basin water quality, and the model has a good reliability. By simulating the human brain in the thought process and analysis mode, the accuracy of water quality assessment is greatly improved, which means that the model can provide a reliable basis for assessing the water quality of the river basin.
