Tunnel excavation is an inevitable process for railroad construction in Korea and it being a one of the major issues of its environmental impact assessment. Ground water flow by tunnel excavation is an important parameter to determine environmental effects. The current method to determine the ground water flow is used a unit number induced a highway construction site. But it does not consider any site characteristics; ground water level, soil properties and others. The purpose of this study is to suggest the determination way of ground water flow considering site characteristics in tunnel construction.
