Development of the River Disaster Caused by the Tsunami —A Disaster Prevention Education Perspective in the Aftermath of the East Japan Great Earthquake and Tsunami—

Abstract

In this paper we suggest a new point of view and development of teaching materials about river flooding caused by a tsunami. Disastrous river flooding was discussed with regard to (1) debris flow, (2) Inundation by river water, (3) Inundation inside the levee, caused by meteorological disaster. The main approach from the ground and the topography as a posterity factor. We give attention to the “East Japan great earthquake disaster” in which the massive tsunami caused by the earthquake flowed backward upriver and brought severe flooding.
We appeal in this paper to the need for “Disaster Prevention Education with regard to the tidal bore caused by a tsunami” that has possibilities to bring a deluge, and we introduce examples of teaching materials.
