Desc<x>ription: 12 carved granite sculptures based on Scanning Electron Microscopy images of diatoms used to determine water quality in urban waterways. The sculptures are sited along a three block long bio filtration landscape strip in downtown Portland, Oregon adjacent to Portland State University. Work created in consultation with the Environmental Studies Department, Portland State University and Portland City Water Bureau. Urban Hydrology integrates storm water purification in a busy urban environment with a beautiful and unusual landscape, and interpretive sculptures that students at the nearby university study in their urban planning, environmental studies, and biology classes. Granite for the sculptures was sourced locally and makes sense along the busy transit mall where less durable materials can be subject to vandalism. The sculptures have been included in presentations at the National Conference on the Study of Diatoms and Water Quality.
