Keywords:flood disaster, disaster monuments, traditional flood evacuation shelter, land history, southeastern part of Gunma Prefecture
This study presents the results of a study on damage, flood risk, and land history in southeastern part of Gunma Prefecture investigated from disaster monuments and traditional flood evacuation shelters.
Disaster monuments: It is known that many floods have occurred in this area and many disaster monuments were erected. In this area, disaster monuments associated with flood disaster occurred in 1742, 1823, 1824, 1910 and 1947. It can be read from the inscriptions and names of the monuments that they were erected to mourn and hold a memorial service for the victims, pass on the lessons learned from the disaster, honor those who worked hard to help the victims, and commemorate the recovery and reconstruction. The existence and process of small ponds along Tone river can be read from old map of 1884 and old topographic maps from the Meiji period onwards.
Floodproof buildings: It is known from many studies that many traditional flood evacuation shelter called "Mitsuka" remained in this area, but the number has decreased in recent years. rapidly declining. The relative height of the embankment from the surrounding ground varies slightly depending on the region, but some have a relative height of close to 3m. In addition, there are many shrines in this area where the main shrine and worship hall are built on embankments (mounds) with a clear relative height of more than 1m higher than the surrounding area.
