Riparian Vegetation and Braided Stream Dynamics
Authors: Efi Foufoula-Georgiou, Chris Paola, Michal Tal, Elizabeth Tilman
1. To study and quantify the interactions between riparian vegetation, channel morphology, and flow dynamics.
2. To investigate how river systems self-organize as a result of these interactions.
3. To investigate spatial and dynamic scaling in braided rivers with and without vegetation.

Ongoing experiments at the St. Anthony Falls Laboratory are designed to isolate the effects of vegetation on braided stream dynamics. These experiments show how a fully braided stream with a noncohesive bed transitions to a single-thread (meandering) system when continuously forced with vegetation. Time-lapse photography and measurements of bed topography, flow depth, sediment output, and flow velocities enable us to study and quantify the morphodynamics of the system associated with this change.

Stream Lab 2008
Authors: Efi Foufoula-Georgiou, Arvind Singh
StreamLab08 experiments were specifically designed to understand and quantify the effect of migrating gravel-bed topography on velocity fluctuations and sediment transport. These experiments provide a much higher resolution and longer duration flow field, bed topography and sediment transport measurements in the case of gravel-bed conditions compared to those of StreamLab06.
