What is a "Flood Hazard Map"?

A “Flood Hazard Map” herein referred to is a map that graphically provides information on inundation (predicted inundation areas, inundation depth, etc.), as well as on evacuation (location of evacuation refuges, evacuation routes, dangerous spots on evacuation routes, etc.) in an easy-to-understand format. The goal is to quickly evacuate local residents in a safe and proper manner in the event of floods. The map is produced and publicized through a joint effort by those in charge of disaster prevention and those in charge of rivers and hydrology in the respective local municipalities. (By “Flood Hazard Map Manual for Technology Transfer”, Ministry of Land, Infrastructure and Transport, Infrastructure Development Institute-Japan)
