Estimated Flood Probability Map

Spatial visualization of the estimated flood probability for a forecast horizon of 0–72 hours, as calculated by the Dynamic Flood Hazard Assessment Model (DFHAM) and displayed through the Inachos system.

The initial view shows the maximum estimated indication per area within the selected 24-hour period. The hourly evolution is available as a second, more detailed view.

Maximum estimated flood probability for the first 24-hour period.

At 100%, the full map is displayed. Use the + / − buttons to zoom in or out. Scrolling is enabled only when the image is larger than the frame.

Colour interpretation – 24-hour maximum indication

The colour classes show the maximum estimated flood probability calculated for each area within the selected 24-hour period.

0–<20% — no colour display

20–<40%

40–<60%

60–<80%

80–100%

This view is summary-based: each cell shows the maximum value that occurred within the corresponding 24-hour period.

Maximum values do not necessarily occur simultaneously across all areas.

Colour interpretation – hourly evolution

The colour classes correspond to levels of estimated flood probability for the selected hourly time step.

Very low probability

Low probability

Moderate probability

High probability

Very high probability

The images correspond to successive time steps of the simulation and are based on the outputs of DFHAM.

The maps constitute a research/pilot estimate and do not replace official warnings or announcements issued by the competent authorities.
