Abstract

Fluvial systems respond to changes in boundary conditions in order to sustain the flow and sediment supplied to the system. Local channel responses are typically difficult to predict due to possible affects from upstream, downstream, or local boundary conditions that cause changes in channel or planform geometry. Changes to the system can threaten riverside infrastructure and riparian zones, which may affect the local ecology. This research focuses on meandering channel patterns and the forces applied to their physical boundaries by the complex three-dimensional (3-D) flow found in meandering bends.
