Flood risk assessment. See where the water goes, before it rains.

In September 2023 Storm Daniel flooded large parts of the Thessaly plain. Floods like this depend on rainfall, soil, rivers, embankments and roads all at once. A flood twin brings them together so planners can test a storm in the model first.

The questions

  • Which roads, bridges and neighbourhoods flood first under a given amount of rain?
  • Which villages could be cut off, and for how long?
  • Where would a new embankment or drainage channel help most?
  • How do farms, water supply and power networks recover after a flood?

What the twin would model

  • Elevation and river networks
  • Rainfall forecasts and past storm records
  • Soil and land use
  • Buildings, roads, bridges and critical services
  • Satellite flood maps from past events, to check the model

Who it is for

Regions and municipalities, water authorities, farmers' cooperatives, insurers and engineers.

Public sources we plan to start from

Listing a source does not mean we have a partnership with it. These are public datasets we plan to evaluate.
