The goal is to advance our understanding of meander morphodynamics in eroding channels enough to develop a general theoretical framework for channel meanders in a variety of environments. A particular focus is the meandering of mixed bedrock-alluvial channels and the role of sediment cover in the mediation of patterns of channel erosion. Such processes are being studied through a combination of field studies, laboratory experiments, numerical simulations and theoretical analysis.
OUTCOMES: Found that the erosion front can be written as an Eikonal equation. Five meeting abstracts have been published.
