Evaluating downstream channel changes in response to a small dam removal on the Calapooia River, Oregon with respect to measurement errors and prior aerial photo observed changes

Creator:

Walter, Cara

Abstract:

The objective of this study was to evaluate the use of aerial photos as a substitute for multiple-year pre-removal field data to assess the downstream channel changes associated with a small dam removal. The Brownsville Dam, a 2.1 m tall concrete dam on the Calapooia River, Oregon, was removed in...

AN ABSTRACT OF THE THESIS OF Cara Walter
Physical Modeling of the Feedbacks Between a Reed Canarygrass (Phalaris arundinacea) Patch, Hydraulics, and Bedform Evolution

Creator:

Elliott, Susan H.

Abstract:

Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...
