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

Moderate — closer to a watercourse or lower-lying terrain

Confidence: high

Height above nearest drainage: -0.7 m
Distance to nearest watercourse: 215 m
Slope: 0.9%

Flash-flood terrain data is derived from OpenStreetMap waterway data. See OpenStreetMap attribution
