Chris Magirl is the Studies Chief at the USGS Arizona Water Science Center. The Water Science Center serves Arizona and the Nation collecting and disseminating high-quality hydrologic data and scientific interpretation, publishing dozens of USGS Series reports and peer-reviewed journal articles each year. The Center also provides critical hydrologic leadership, working with cooperating state, local, and federal agencies, tribes, and academic researchers.

From 2000–2015, Chris was a researcher and project chief at the USGS working on multiple projects involving fluvial geomorphology throughout the western United States. Chris has researched rapids of the Colorado River in Grand Canyon and Cataract Canyon, the Elwha River dam-removal project, sediment production from Mount Rainier and other glaciated stratovolcanoes, and the interactions between geomorphology and aquatic ecology pertaining to salmon. Chris was also deeply involved in the USGS response to the March 22, 2014, Oso Landslide of Washington State.

Before joining the USGS, Chris was an engineer and R&D project manager with the Hewlett-Packard Company building color inkjet printers. As a youth, Chris was fascinated with fluid mechanics and thermodynamics, thunderstorms, flash floods, airplanes, rockets, and rivers. For over 25 years, Chris has been fortunate to enjoy fluid mechanics and thermodynamics in his professional research and engineering career. Chris has studied directional solidification, the microscopic droplet ejection, landslides and debris flows, extreme rainfall events, and the hydraulics of rapids—it’s all fluid mechanics, just different scales and viscosities.
