The multifunctional blue-green design group at Eawag focuses on developing integrated engineering design and decision making strategies for blue-green infrastructure at the neighborhood scale. We combine laboratory analyses, field monitoring campaigns, statistical analyses and simulation models to quantify the performance of different BGI elements and configurations in the environment for numerous design objectives, including stormwater management, heat mitigation, species diversity. We also evaluate how BGI would function in a future climate using high-resolution climate scenarios. This research advances the state of the art by linking complex models and information into a systematic framework, thus moving away from traditional siloed and ad-hoc methods, towards a better, interdisciplinary approach.
