Urban Hydrologics derives its inspirations and design language from the unique characteristics of fluvial geomorphology. The movement of water in nature creates inspiring forms. Scientific research within fluid mechanics helps us understand the mathematics of water, revealing the geometries and formal expressions which give us the inspiration to generate performative designs. Diverse reactions and interactions of water, from chemical, biological, and physical, all the way to molecular structures, are well understood by scientists. We propose to use these elegant forms to generate a unique language for urban systems, landscapes, networks, and products at diverse scales.
