Jonathan Friedman is a Hydrologist at the Fort Collins Science Center.
Since joining the Fort Collins Science Center in 1993, Jonathan has devoted his career to studying interactions among riparian vegetation, river flow and channel change. Present research topics include use of riparian tree rings to reconstruct past river flow, quantification of federal reserved water rights, and determination of the effect of riparian vegetation on bank stability.
