abstract
A village of Kashobara was established by new reclamation work for rice field in early 19th-century in the southern part of Saijo Basin, Higashi-Hiroshima City, Southwest Japan. Local villagers built a pond named "Nakanotao pond" for irrigation close to the village. Because its water was always little due to its too small catchment area, it was very difficult to crop rice properly. Then local villagers made an irrigation channel to put additional water into the pond from out of its catchment. As a newly tunnel for irrigation was made in 90 years ago, the channel has been abandoned over 30 years. The objects of this study are 1) mapping of the abandoned channel by geophysical field survey, and 2) analysis of historical record related the abandoned channel. This study contributes a record of local heritage of civil engineering, and is regarded as a pioneer study for mapping of abandoned channel, numbers of which will increase in Japan.
