elderly welfare facilities
Typhoon HAGIBIS in 2019
In the heavy rain disaster caused by typhoon HAGBIS in 2019, the collapse of the Chikuma River embankment caused widespread inundation damage in Nagano City. We conducted an inundation trace survey, the flood inundation calculation, and interview surveys of 6 elderly welfare facilities which were damaged by inundation. From the results, the relationships between the evacuation behavior of each facility and the inundation process were analyzed. In addition, we considered the issues of evacuation safety planning in the event of the largest expected flood.
