How rainfall accumulation, NOAA alerts, soil moisture, SAR flood extent, and terrain drainage combine into one flood risk score.
🧠 OPEN BRAIN DASHBOARD LIVEEvery second, Christchurch's flood risk score recalculates. A rainstorm brewing over the Southern Alps. Soil already waterlogged from last week's deluge. A NOAA alert flashing red. Your Brain Dashboard synthesizes seven real-time signals—not guesses—into a single number that tells you exactly how close your city is to catastrophic overflow. This is how it works.
The Pandita flood risk engine does not treat all water warnings equally. Instead, it weights incoming signals by predictive power, then layers them through a soil-saturation multiplier that captures the hidden vulnerability: a watershed already full is far more dangerous than one that is dry.
Think of the flood score as a weighted sum, not a simple average. Each signal feeds into the engine independently, then a soil saturation multiplier amplifies the total when groundwater is already high.
SAR (Synthetic Aperture Radar) flood extent contributes 15%—it detects standing water even under cloud cover, giving a real-time snapshot of which areas are already inundated. Elevation and drainage topology account for 5%, anchoring the model to physical geography.
When NOAA issues a flood warning, the engine doesn't just add 25 points. It flags a confidence boost: official meteorologists have validated a dangerous pattern. This triggers secondary signal reinforcement—if rainfall + NOAA alert + high soil moisture all align, the multiplier can push the final score 40–60% higher than rainfall alone would suggest.
This is where Pandita's model diverges from simple weather forecasts. Dry soil + heavy rain = manageable. Wet soil + heavy rain = flood. The engine continuously monitors soil moisture indices. When saturation exceeds 70%, a multiplier (typically 1.3–1.8×) scales the combined signal upward. Christchurch in 2024, following consecutive rainy months, has seen this multiplier active for weeks—turning a moderate rainfall event into a genuine flood threat.
