Tool designed to help local authorities to explore pluvial hazard & risk from extreme convective precipitation events and subsequent flooding due to surface rainwater accumulation which the existing urban drainage system is unable to absorb. The tool delineates the areas prone to flooding under different rainfall intensities and persistence and estimates the damage to physical assets such as buildings’ structures and content. The tool is amendable to inform adaptation measures such as green urban regeneration and natural water retention measures by means of green roofs and green urban areas. The application of the tool is amendable to help users to identify existing green urban infrastructures and identify areas suitable to extend them, while controlling for the potential to reduce flood damage or share of affected population.
The complexity is variable and depends on the extent to which the users frame the analysis. It is low if the users access the service from a dedicated platform which allows to run the models and assess performance of some risk mitigation solutions. It is medium to high if the users prefer to run the underpinning open source models and control the implementation of the green regeneration strategies and green infrastructure design
The tool enables a better appreciation of pluvial hazards and risks and empowers the users to design solutions to boost local resilience. The benefits vary across the user groups, for example urban and regional authorities gain insights into climate risks as an input to climate adaptation and disaster risk reduction strategies; businesses draw insights about how their exposure to physical climate risks and local action groups obtain insights about how the neighborhood green regeneration strategies contribute to reducing the risks. The results of the tool contribute to building a knowledge base of climate related impacts & risks.
This tool is ready for use in any location in the world. Basic use of the tool requires little effort, on the order of 3 to 5 person-days. However, advanced use of the tool varies widely depending on the specific needs and level of analysis performed, including harmonisation and pre-processing of local data, statistical analyses of rainfall, processing of climate change scenarios, and selection of greening scenarios. Such an analysis can vary from approximately 10 person-days to several person-months. The pluvial flood module has a fee for full-version use. Prices vary from 3 to 20 €/Km2 per year based on the required resolution.
The tool can be used in the following Triple-A phases:

The tool is complementary to other climate-related urban hazard & risk assessment services (e.g., Thermal assessment tool or Social Vulnerabilty Index), serve as an input for other services such as dynamic integrated flood insurance or community flood resilience support system model and help to identify tailormade adaptation & DRR solutions.
