Lidar Assessment Of Sediment Transport Related To The Removal Of The Marmot Dam, Sandy River, Oregon, Carl Daniel Matzek
All Master's Theses
Four Aerial LiDAR survey were used to examine the impacts of the 2007 removal of the Marmot Dam on the Sandy River, Oregon. Geomorphic Change Detection software was used to answer three project goals: 1) to investigate how the dam removal affected sediment distribution in the lower reach of the river, several km downstream of the dam, 2) to determine whether the pulse of sediment from the dam removal created a detectable, successive downstream accumulation of sediment through time, and 3) to assess the effect of natural high-flow events on the sediment distribution related to the dam removal. The results …
