Flood
River flood
No satellite flood observation covers this location yet
River hazard is scored only against a single 2024 satellite-observed flood event covering four northern Thailand provinces (Chiang Mai, Chiang Rai, Lamphun, Phayao). "Unknown" outside that area means no observation exists yet — it does not mean the area is safe.
Flash flood
Low — some distance from watercourses or higher ground
Confidence: high
- Height above nearest drainage: -46.1 m
- Distance to nearest watercourse: 2703 m
- Slope: 0.7%
Flash-flood terrain data is derived from OpenStreetMap waterway data. See OpenStreetMap attribution
