🌊 방콕 침수 지도
어느 구가 우기마다 잠기는지, 어느 구가 안전한지. 콘도 사기 전에 반드시 확인. 2011년 대홍수 + BMA 배수국 + JICA 보고서 기반.

근거: BMA 배수국 + JICA 보고서 + 2011년 대홍수 침수 범위. 좌표 단위가 아닌 구(khet) 단위 베이스라인. 동네별 차이 있음.
왜 구 단위인가?
동네/도로 단위 정밀 침수 GeoJSON은 BMA가 일반 공개하지 않습니다. 구 단위 베이스라인은 거시적 위험도 판단에 충분하며, 같은 구 안에서도 도로 고도/배수 인프라에 따라 차이가 있으니 매수 전 현장 답사 필수.

Bangkok flood risk — frequently asked questions
- Which Bangkok districts have the highest flood risk?
- Districts rated Level 4–5 (highest risk) include Bang Khen, Bang Khun Thian, Don Mueang, Khlong Sam Wa, Lak Si, Lat Krabang. These areas experienced sustained inundation during the 2011 great flood and face recurring monsoon flooding. Each condo page shows its district's exact flood level.
- Which areas of Bangkok are safe from flooding?
- Districts rated Level 0–1 (lowest risk) include Bang Rak, Pathum Wan, Pom Prap Sattru Phai, Ratchathewi, Sathorn. These areas have elevated terrain and robust BMA drainage infrastructure. Pathum Wan (Siam/Phloen Chit), Watthana (Asok/Phrom Phong), and Bang Rak (Silom) are typically the driest zones.
- How is Bangkok flood risk measured?
- RealData assigns each of Bangkok's 50 khet (districts) a flood risk level from 0 to 5 using three primary sources: BMA (Bangkok Metropolitan Administration) Drainage Department records, JICA flood frequency reports, and 2011 great flood inundation maps. Level 0 = no observed flooding; Level 5 = repeat full-area inundation during monsoon season. The layer is reviewed annually after each BMA monsoon report.
- Did the 2011 Bangkok flood affect all areas of the city?
- No. The 2011 great flood primarily affected outer districts north and east of Bangkok — including Lak Si, Don Mueang, Lat Phrao, Nong Chok, and Khlong Sam Wa — which saw waist-deep flooding lasting weeks. The central business districts (Silom, Sukhumvit, Siam) were largely protected by elevated terrain and the King's Dyke flood barriers. RealData's flood risk model is calibrated against these 2011 records.
- Is Sukhumvit safe from flooding in Bangkok?
- Sukhumvit spans multiple districts with varying flood risk. Lower Sukhumvit (Khlong Toei, Watthana — BTS Asok to Phrom Phong area) carries Level 1–2 risk and stayed dry in 2011. Upper Sukhumvit extending toward On Nut, Phra Khanong, and Bang Na has Level 2–3 risk with occasional street flooding during heavy monsoon rains.
