Recognising hazard areas

Flood hazard maps show:

• the spatial extent of floodings during flood events
• the hazards due to floodings
• the location of flood protection installations

The hazard itself considers both the probability of a flood occurring and the intensity of the potential flood (water depth * flow velocity). In the TIMIS flood project, the degree of hazard is classified into four hazard stages: substantial, moderate, minor as well as residual.
