基于机器学习的输水河道沿线地下水位预测分析OA
Prediction and Analysis of Groundwater Level Around Water Conveyance River Based on Machine Learning
引江济淮工程为重大水资源配置工程,其河南段由安徽省西淝河向上游供水,其中利用清水河输水河道输水 48.40 km,工程运行将引起地下水位变化,因此研究河道沿线地下水位变化对工程安全稳定运行的影响.研究使用BPNN、SVM、XGBoost算法建立机器学习模型对输水河道沿线地下水位进行预测,对比不同模型的训练效果并选择最优预测模型,分析距河道不同垂直距离对地下水位预测的影响,结果表明:SVM预测地下水位效果最优,距河道垂直距离对地下水位预测效果不产生影响.
The water diversion project from the Yangtze River to the Huaihe River is a major water resources allocation project.Its Henan section supplies water from the Xifei River in Anhui Province to the upstream.The project uses the Qingshui River to transport water for 48.40 km,and the operation of the project will cause the change of groundwater level.Therefore,the influence of the change of groundwater level a-round the river on the safe and stable operation of the project is studied.In this study,BPNN,SVM and XGBoost algorithms were used to es-tablish machine learning models to predict the groundwater level around the water conveyance channel.The training effects of different models were compared and the optimal prediction model was selected.The influence of different vertical distances from the channel on the prediction of groundwater level was analyzed.The results show that SVM has the best effect in predicting groundwater level,and the vertical distance from the channel has no effect on the prediction results of groundwater level.
