Publications
The staff at GEO Morphix have developed and participated in many rigorous research programs, and maintain ties with several academic institutions.
Our research interests focus on the fundamentals of sediment transport, bedform and channel evolution, turbulence and hydrodynamics, development of innovative sedimentology and ecological field measurement techniques, urban impacts on rivers, over-wintering habitat, and benefits of restored riverine systems.
Below you will find a partial list of our contributions through peer-reviewed publications, presentations, and posters. Participating staff’s names are in bold.
