Description

We applied muography for inspecting rock-filled debris dams that are consolidating river basins and allowing erosion control and flood protection of mountainous areas. The mass density image of a debris dam in the Karasugawa river, Gunma, Japan was produced with a spatial resolution of 0.5 m × 0.5 m. The comparison of density data reconstructed by muography and gamma-ray logging suggest the internal deterioration of the dam in a region where cement released out from the embankment body.
