I’m a second year Master’s student examining the affects of floodplain constriction by artificial levees to sediment transport processes and channel morphology. My research focuses on a leveed section of the Snake River between Moose and Wilson, WY, as an example of an intensively managed, braided river system, both to address issues specific to this reach and to gain more general insight on the effect of constriction by levees on the morphodynamics of high-energy river systems. The purpose of the levees is to provide flood protection for property owners, but these structures also have had the unintended consequences of destabilizing the river and degrading riparian, aquatic, and wetland habitat. In an effort to understand the physical processes that are driving morphological change in this system, I’m using numerous datasets, including: LiDAR data to quantify morphological change; a tracer study, using PIT tags, to track entrainment of sediment; and hydraulic modeling. Stay tune for results!
