Asami-gawa River Flood Hazard Map

Following the increase of large-scale flood disasters, the Flood Control Act was revised in 2015, and the assumed flooding areas of the Asami-gawa River areas, managed by Oita Prefecture, were reviewed. (Announced by Oita Prefecture in April 19, 2019)

This is a prediction of flooding conditions resulting from river overflow due to the assumed maximum scale of rainfall (maximum rainfall of 624 mm in 6 hours) to occur at Asami-gawa River.

Residents are advised to be prepared for disasters by using the “Asami-gawa River Flood Hazard Map” to gain correct knowledge on disaster risks and raise their awareness of disaster preparedness based on the idea of "protecting your own lives."

Please contact the offices below for the exact location of predicted flooding areas around the Asami River.

Checking the area you live in (water depth guide)

The flood hazard map shows the expected water depth by colour when the rivers overflow due to heavy rain.

Check the depth for the area you are living in to see which areas are flooded and how much (the depths are shown on an image of a 2-storey house).

Water Depth	Extent of Flooding
5.0m or higher
3.0m – less than 5.0m	Flood waters reaching the 2nd floor
0.5m – less than 3.0m	Flood waters reaching the 1st floor
Under 0.5m	Flooding under floor level Roughly up to the height of an adult’s knee

Using the Hazard Map

The flood hazard map is a collection of information showing places to evacuate in case of flood damage, and points to be aware of.

We never know when a natural disaster will occur. Use the hazard map to discuss plans with your family and community, so that you can keep calm and work together in an emergency.

We will inform you of evacuation information for flood damage, landslides, etc. at 5 alert levels!

The way of transmitting disaster prevention information for floods and landslides will be changed!

In March 2019, the Cabinet Office revised the “Guidelines for Evacuation Recommendations” and from June 2019, we will send notifications for evacuation information at 5 different alert levels.

"Alert Level 1 to 5" will be issued at the time of Heavy Rains or Typhoons!（English）
