Japan to provide flood risk maps for four Southeast Asian countries
Japan plans to start providing flood risk maps for Vietnam, Indonesia, Thailand and Cambodia next fiscal year to help the Southeast Asian countries reduce damage from flooding. The maps will use satellite observation data to predict flooding caused by heavy rainfall.
The Japanese Ministry of Land, Infrastructure, Transport and Tourism already published flood risk maps for various parts of Japan, showing the frequency and depth of inundation caused by flooding. Based on observation data collected on the ground, including by rainfall gauges, the maps show the risk of inundation from heavy rainfall likely to occur every 10, 30, 50, 100 and 150 or 200 years, with the information to be used to facilitate smooth evacuation and community planning.
