RainGain

To prevent the severe pluvial flood damage

The project’s aim is to obtain fine-scale rainfall and flood data at the urban scale: a level of detail at which such information is currently lacking. The availability of fine-scale rainfall and flood data will enable urban water authorities to adequately cope with peak rainfall and will help to prevent the severe pluvial flood damage that in the past decades has been associated with these events.

Rainfall radars are the only measuring devices that provide space-time estimates of rainfall that can be used for this purpose. This technique has only recently been developed to become sufficiently detailed to be applicable to the scale of urban areas. This innovative technique will be brought to implementation in water management practice at pilot locations in the partner countries. The installation of new radars for fine-scale rainfall measurement at pilot locations in Rotterdam and the Paris Region is foreseen as part of the RainGain project; a similar technique has been installed in Leuven several years before. In the UK, a novel, superresolution protocol will be applied to obtain detailed rainfall data from the C-band radar of the MetOffice.

The fine-scale rainfall data will provide urban water managers with detailed peak rainfall information at temporal and spatial scales appropriate to the fastness of urban run-off processes. The information will be applied in  in flood prediction models at pilot locations in the four participating countries to identify flood-prone locations and develop effective solutions for better flood protection such as early warning systems and optimised, real-time storage basin operation. These will in their turn be tested based on the detailed rainfall data and flood models. The end users of the rainfall equipment, data and models will be trained so they will be able to take over the project deliverables and to resume responsibility in operation and management.
