Description: Scope/Content: Abstract: Introduction The removal of the Marmot Dam in 2007 was an attempt by Portland General Electric (PGE) to restore the SandyRiver, Oregon to its natural state. Since the dam's removal, numerous elevation changes due to sediment transport have occurred. To observe these elevation changes, scientists have collected Light Detection and Ranging (LIDAR) data for the years 2006-2008. Objective: To determine possible sources of uncertainty in LIDAR data and to discern any uncertainty (in feet) in the Sandy River's Revenue Bridge area LIDAR data. Research Area: Revenue Bridge area (Reach B1) of the Sandy River, Oregon.
