The water source of the system is very important for the socio-economic development of the localities in the study area. However, water pollution tends to increase in both scope and extent, indicators of COD, NH4+, PO43- and Coliform have a higher increase than other indicators. COD content increased 8.6 times NH4+ increased 2.48 times
PO43- increased 4.15 times and Coliform increased 91.6 times. Every year, surface water quality is monitored (mainly in the Winter-Spring crop) to serve the drainage. Water quality monitoring methods are mainly traditional methods that are time consuming and labor intensive and often provide limited information on water quality. In this study, we will evaluate the potential of deep learning algorithms in predicting water quality parameters of Bac Hung Hai irrigation system based on field measurements (temperature, pH, DO and turbidity). Research results show that deep learning algorithms can make accurate and fast predictions for parameters BOD5, NH4+, PO43- and COD. The models are highly accurate (from 75% to 85%), and provide meaningful results. The study also demonstrated the potential of deep learning algorithms to improve water quality forecasting and highlighted the importance of selecting suitable deep learning algorithms for different water quality parameters.
