Mountainous tunnel drainage can impact groundwater and human life. A numerical model was used to predict these impacts in northern China. The drainage changes groundwater flow and can reduce spring discharge by up to 25%. Aquifer storage resources decrease due to tunnel drainage, but negative effects can be reduced with strong drainage.
