In Japan, the groundwater flow system study in a bedrock aquifer is not so popular because of its minor storage capacity of the aquifer body as the groundwater resources. However, the development of the recent underground civil structure with utilizing groundwater characteristics such as the underground oil storage cavern and the environmental hydrological assessment of an underground tunnel construction begin to ask the more precise information about the groundwater flow system in the bedrock aquifer. This information is very useful to accumulate the knowledge about the groundwater flow system in the bedrock aquifer of a mountainous body. In the present paper, the author reports the groundwater flow system in the bedrock aquifer revealed not only by the field survey, but also by the computer simulation, mostly based on the author’s experience in bedrock groundwater survey.
