Cities are becoming more vulnerable to flooding because of rapid urbanization and increasing rainfall extremes due to climate change. There is an increasing need for flood forecasting and warning systems for cities. Local authorities, however, often lack both the required expertise and tools to set up such systems. We offer the technology and support to set up flood warning and real-time control systems to minimize flood risks.
Developed by Sumaqua
The system provides real-time nowcasts (= short term forecasts) of extreme precipitation and urban flooding. It consists of four components: a real-time nowcasting system for extreme precipitation based on high-resolution radar data from compact X-band radar, a hybrid data and model based system for urban inundation modelling, a risk assessment module, and a warning system. The nowcasting system is applicable to any city or urban area.
See more information about this level and the TRL and SRL levels.
The urban flood nowcasting system makes use of 4 innovative components. (1) A system for extreme precipitation short-term forecasting applying X-band radar technology. (2) A fast and computationally efficient urban flood modelling and mapping system, based on a hybrid data/model based approach. A detailed 1D-2D nested model for the urban drainage system and the surface runoff and inundation system is complemented by a surrogate conceptual framework for fast and efficient computation. (3) Urban flood risk assessment applying functions describing the socio-economic consequences, specifically valid for urban areas. (4) A warning system, taking uncertainties in the extreme rainfall and urban inundation nowcasts into account.
Limitations/conditions under which this innovation does not work or is less effective
Sufficient local rainfall (e.g. rain gauges, radar) data have to be available, or a location found to install a local low-cost city radar based on X-band technology. Sumaqua website
Added value
In comparison with existing approaches, our system is based on fast and efficient modelling approaches. By combining a model and data based approach, high accuracy can be guaranteed.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.
