Design and deployment of stormwater nature-based solutions (BGI) for resilient and liveable cities

GreenStorm targets nature-based solutions designed to manage stormwater (NBSsw) as a means of urban transition, with a specific focus on climate adaptation, resilience of urban vegetation, but also enhanced social benefits.

The hydrologic and thermal performance of NBSsw during present and future climate extremes (high intensity rainfall, drought, heat waves, frost/thaw) will be assessed for a range of NBSsw structures and a wide span of European climates, by coupled monitoring / modelling.

Improved NBSsw structures, and pathways for their acceptable implementation in urban areas will be developed based on co-creation workshops with all relevant stakeholders (professionals and citizens).

A real case study in Copenhagen will serve to demonstrate NBSsw implementation in a community engaged approach and, based on a cross analysis with data and feedback from Paris, Athens, Genoa and Östersund, will allow to identify drivers for NBSsw upscaling.

Based on these results, potential for widespread implementation of NBSsw at large urban catchment scale will be analysed in the 5 partner countries (France, Denmark, Sweden, Greece, Italy) and the hydrologic/hydraulic and thermal benefits will be modelled.
