This dataset corresponds to the flood hazard maps for the Brussels-Capital Region, in accordance with Directive 2007/60/EC of the European Parliament and of the Council of 23 October 2007 on the assessment and management of flood risks. It is made of16 geometric classes.

These flood hazard maps show the areas that may be flooded by watercourses (fluvial flooding), as a result of rainwater runoff during heavy rainfall (pluvial flooding), or by sewer overflow at the surface onto public roads (the latter are not fully available for the region). And underground flooding resulting from a groundwater table close to the surface.

These maps show the extent, water levels and flow velocities of the areas that will be flooded under various scenarios: a return period of 25, 100 and 100 years, and a climate change scenario (corresponding to a hundred-year rainfall event from 2100 onwards, based on a climate warming trajectory of up to +3.5 °C).

Please note that these maps have no regulatory value.
