The quality of groundwater changes depending on such factors as the source of groundwater, the path of flow, and the residence time. Because of this, one can use such water quality data to classify flow systems and predict paths of groundwater flow.
This report will describe case studies regarding groundwater sources, paths of groundwater flow, and residence times, that used groundwater quality and were conducted in three engineering fields: dams, tunnels, and underground research of radioactive waste disposal. Furthermore, upon consideration of the current status of and problems in studies of groundwater flow in these engineering fields, the report will describe what is expected for future hydrological and groundwater studies in the fields of science.
