How rainfall accumulation, NOAA alerts, soil moisture, SAR flood extent, and terrain drainage combine into one flood risk score.
🧠 OPEN BRAIN DASHBOARD LIVEChristchurch woke to sirens on March 15, 2025. The Avon River had crested 2.3 meters above normal—but here's what most residents didn't know: the flood risk score on Pandita Data's Brain Dashboard had been climbing for 72 hours before the first drop fell. Not because of hype. Because of physics. Every sensor feeding that score was reading the same invisible threat: ground already saturated, atmospheric rivers queued up, and drainage systems running at capacity. This is how we see floods before they arrive.
The Brain Dashboard's flood risk score isn't a guess. It's a weighted blend of five independent signals, each measuring a different piece of the flood equation. Think of it as a diagnostic panel in an ICU—no single readout tells the whole story, but together they reveal the patient's true condition.
The five signals are normalized to 0–100 scales, then weighted and summed. The result: a single number between 0 and 100 on the Brain Dashboard, updated every 15 minutes.
When NOAA issues a Flood Watch or Warning, the scoring algorithm automatically applies a multiplier (+15% to +40%) based on alert severity. This prevents false lows during official emergency periods and ensures the dashboard reflects institutional expertise alongside sensor data.
Here's where many flood forecasts fail: they ignore what happened yesterday. In Christchurch, March 2025 saw 120 mm in the first week of March. By March 12, soil moisture across the Canterbury Plains was already in the 85th percentile. When the next 60 mm event arrived on March 14, it didn't percolate—it ran off immediately into tributaries and the Avon.
The Brain Dashboard captures this through a soil saturation multiplier: if soil moisture is in the top quartile, the rainfall and alert weights increase by 1.3×. Dry ground absorbs. Wet ground floods.
