Collaborative Research: A field, laboratory and theoretical study of mixed bedrock-alluvial meandering rivers

Lead PI: Dr. Colin P. Stark

Unit Affiliation: Marine Geology & Geophysics, Lamont-Doherty Earth Observatory (LDEO)

September 2011 - August 2015
Project Type: Research

DESCRIPTION: 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.
