Abstract
Fukushima basin is composed of alluvial fans covering lake deposits. Mesuring the depth of the water table in wells, the author obtained the following results.
The ground water flows from the west to the east and nourishes the Abukuma. The distribution of the ground water table is generally parallel to the surface topography. Two ground water valleys are found, which are buried valleys of the paleo-Sukawa. Influent seepage of the Matsukawa is important as the source of ground water and springs at the ends of fans.
