Chiang Mai launches CMFlood system to bolster urban flood early warning

 | Tue 26 May 2026 16:25 ICT
Chiang Mai is stepping up its flood preparedness with the formal promotion of CMFlood, an urban flood warning system developed by Chiang Mai University in partnership with a network of allied agencies.

The push follows the severe flooding of 2024, when the Ping River at the P.1 station reached 5.30 metres, causing widespread damage across the city.

CMFlood is designed as a centralised decision-support platform offering five core components: advance water level forecasting; a flood hazard map; a flood depth map; over 300 Flood Pole water level indicators installed across at-risk areas; and a real-time monitoring dashboard accessible online. The system also features Flood Marks — physical markers showing historical peak flood levels — to help residents assess risk in their immediate area. All data is consolidated on a central database at https://watercenter.cmu.ac.th/chiangmai/cmflood/warning.
