Our Focus

We are professional earth scientists specializing in geomorphology and process sedimentology. We focus on river and shoreline restoration, erosion hazard delineation and mitigation, and projects that require an in-depth understanding of erosion, sedimentation and sediment transport.

Our team of industry leaders provides observation-rich answers based on a balanced application of quality science and years of experience to achieve practical, implementable and acceptable solutions for all stakeholders. A successful project is one that meets or exceeds our client’s objectives.

  • Geomorphology. Earth Science. Observation.


  • Watersheds. Rivers. Coasts.


  • Sedimentary Processes. Hydraulics. Morphology.


  • Measurement. Modeling. Prediction.


  • Characterization. Protection. Restoration.

GEO Morphix’s publications/academic involvement

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.
