Groundwater quality prediction has practical significance for the prevention of water pollution. Based on the exogenous variables which are effective on water quality indicators, this paper proposes a new method with new effective parameters based on LSTM RNN for groundwater quality index prediction. The effective parameters on the groundwater quality index include rainfall rate, temperature, and humidity, and groundwater abstraction was collected. Monthly time series data selection was done from five different locations in the Damavand region in Iran from 2009 to 2021. Neural network architecture is tested by "f-score" tested to obtain the best neural network performance. A comparison of the real value and the result of the prediction show that the water quality index prediction has been done sensibly and quite properly in most cases.

地下水水质预测对水污染防治具有重要的现实意义。基于对水质指标有效的外生变量,提出了一种基于LSTM RNN的地下水水质指标预测新方法。影响地下水水质指标的有效参数包括降雨率、温度和湿度,并收集地下水抽水量。2009年至2021年,在伊朗达马万德地区的五个不同地点进行了月度时间序列数据选择。对神经网络结构进行f-score测试,以获得最佳的神经网络性能。实际值与预测结果的比较表明,在大多数情况下,水质指标预测是合理的。
