The Zofnass Information Tool provides learning about the urban water systems and the sustainable intervention opportunities that address climatic risks and contribute to the sustainability of our cities.
Developing non-expert awareness on urban water systems and the intervention opportunities can facilitate the creation of collaborative platforms for different stakeholders involved in cities to work in unison.

Based on research findings from a data-driven approach on urban water management and green infrastructure, here we present how to learn about the urban water infrastructure system of the City of Chelsea, MA - our first case-study city - and what are the intervention opportunities for green infrastructure.

The Zofnass Program provides frameworks for a holistic approach to sustainable infrastructure and cities. With this tool, the planning strategies are synthesized with data and computation. Visitors can learn about the water system, its performance, and the geospatial synergies, while they can explore the range of green infrastructure opportunities by their spatial and quantitative impact.
