JAEA Reports

Radionuclide migration toward human society through geologic processes is to be assessed as part of long-term safety assessments of geologic disposal for radioactive waste. This study was conducted to develop methodologies of boundary delineation for regional groundwater flow system. Geographic Information System, GIS, was applied to Miyakoji in the Abukuma as an area of interest. The present study revealed that, taking the groundwater flows and fracture characteristics of the area into consideration, the groundwater flow system in Miyakoji drainage basin should be bounded by the Otakine mountain area and the northern part of Tokoha drainage basin, which occupies a larger area than understood before.

Oral presentation

Boundary delineation for regional groundwater flow through GIS; A Case of crystalline rock area

no journal, , 

This study was conducted to develop methodologies of boundary delineation for regional groundwater flow systems. Geographic Information System, GIS, was applied using available topographic, geologic and hydrologic data for an area of interest. An area of this study was selected as the area, for the reason of its simple geologic setting formed by crystalline rocks and topographically gentle hills of drainage basin. The present study revealed that, taking the potential groundwater flows and characteristics of fractured zones in the area into consideration, the groundwater flow system in the area of this study drainage basin should be bounded by the highest Mountain in the area and the northern part of neighboring drainage basin. The delineated area is larger than understood before.
