This paper reports the results of investigations of the damage to the embankments in the Naruse River caused by a great earthquake originating in the north of Miyagi prefecture on July 26, 2003.
A geophysical exploration in the damaged section found that the body of the embankments in the Naruse River was generally loose and weak.
In the embankments in the Naruse River, seepage water easily accumulates and can hardly be drained because they contain the old embankments and revetments.
Based on the investigation results, measures were assessed for reinforcing the embankments in the Naruse River.
