REPORT OF THE MONOBE RIVER FLOOD IN JULY 2018

Abstract

 During heavy rain in July 2018, record flood occurred in the Monobe River (Monobegawa) like other rivers. Fortunately, no serious inundation occurred, but the importance of prior measures for flood control and the difficulty of encouraging evacuation behavior in rivers with low flood frequency were recognized again.

 In this report, we report the summary of the flood and the flood forecast, the possibility that inundation damage had occurred without river improvement in recent years, the evacuation behavior during heavy rain in July, 2018, and the resident awareness survey in the Monobe River (Monobegawa). In addition, this report mentions the importance of flood countermeasures that combine hard (structural) measures and soft (non-structural) measures.
