Urban Hydrology, Granite sculpture series at Portland Transit Mall, United States.
Urban Hydrology is a series of twelve granite sculptures positioned along three city blocks of Southwest Sixth Avenue near Portland State University. The works integrate seamlessly into the transit corridor and create stopping points throughout the public pathway.
The sculpture series was commissioned in 2009 as part of improvements to Portland's transit infrastructure. The project resulted from collaboration between public agencies and the university to enhance the public corridor.
Each sculpture draws inspiration from electron microscope photographs of diatoms, which scientists use to evaluate water quality in urban waterways.
The installation spreads across a walkable public corridor that is easy to explore on foot. Visitors can move through the series at their own pace and spend time observing individual pieces.
Each sculpture draws its form from magnified photographs of diatoms, microscopic organisms that water scientists use to monitor urban water quality. These invisible life forms become visible through the granite pieces, connecting scientific observation to public art.
