The department of Hydrology of the university of Leuven elaborated a 2-D sewer surface inundation model for the city centre of Antwerp. Although very useful in itself, by raising the preparedness and the logistics of the first responders, and by providing a lever for mitigation, the 2-D model is a climate concept, which does not take into account actual meteorological data.
Technology validated in lab.
Basic technological components are integrated to establish that they will work together. This is relatively “low fidelity” compared with the eventual system. Examples include integration of “ad hoc” hardware in the laboratory.
Compact high resolution X-band radar is developed. Inundation risk maps have also been developed. Both need to be interlinked now.

How does it work?

An X-band radar provides us with a forecast of heavy rain: expected intensity and expected neighbourhoods. Radar images (if available, validated by pluviometer data) are transferred into discharge amounts, and then put into a 2-D GIS-model, taking into acount two dimensions: surface relieef and sewer capacity. This enables us to predict where the most severe flash floods will occur.
