dc.description.abstract Past research on meandering rivers with skewed planform geometries has shown that skewness orientation impacts patterns of hydraulic conditions and morphological changes. The purpose of this work was to expand on that knowledge by testing different degrees of skewness and discharge conditions. A laboratory flume was used to test two unconfined skewed alluvial meandering river channels with opposite skewness orientations. Values of skewness were chosen to be different from past research for later comparisons. Experiments began at a low flow condition until equilibrium was achieved, at which time the discharge was increased to a higher value until equilibrium was reached again. Data was collected for flow rate, flow depth, and bedload transport, while elevation data was obtained using photogrammetric techniques. Results showed evidence for increased stability in the upstream skewed orientation with larger flow resistance, while the downstream skewed orientation adjusted towards a more symmetric (ex. non-skewed) channel over time. en_US
