Floods
ADAM monitors floods globally, combining forecast-based alerts (GLOFAS) with satellite-derived flood mapping after an event. Long-duration events are monitored weekly for up to one month.
Draft
Skeleton page. Detailed walkthrough and screenshots to be added.
Data sources
- GLOFAS — Global Flood Awareness System (JRC) — forecast alerts
- Copernicus EMS — Emergency Management Service (rapid mapping)
- FLOODSCAN and CSDMS — flood observatories
- GEE / GCS — Google Earth Engine compute for satellite-derived mapping
What ADAM produces
- Flood Forecast Map — GLOFAS-derived early warning
- Flood Map (post-event) — satellite-derived flood extent within 72h
- Population Impact Map and Population Impact Table
- Cropland Impact Map and Cropland Impact Table
How to read the outputs
- Forecast (probabilistic) vs observed (satellite)
- Confidence: cloud cover, sensor revisit time
- How exposure differs from damage estimates
Typical alert workflow
- GLOFAS forecast triggers a pre-event alert
- After flood onset: satellite-derived mapping within 72h
- Updated impact tables disseminated
- For prolonged events: weekly updates for up to one month
