Andy Fallon

Fluvial Geomorphologist

At Inter-Fluve, we often use the phrase “From Source to Sea” to describe the breadth of our work—from high mountain landscapes to estuaries and coastal wetlands. It’s hard to imagine anyone embodying this concept more than Andy, who has done everything from hiking the entire Appalachian Trail to monitoring nesting sea turtles in Florida.

As an undergraduate and master’s student, Andy researched the impact of Tropical Storm Irene on the Connecticut River and sediment transport and erosion around Plum Island, Massachusetts. After graduating, he spent a few years as an environmental consultant in New England and the Gulf Coast. His work there largely focused on coastal and estuarine assessment and monitoring. A coastal restoration project coupled with an encounter with Inter-Fluve through our work on the Coonamessett River sent him in a slightly different direction, and he returned to school for a doctorate in Fluvial Geomorphology. He started working on-call for Inter-Fluve in 2023 during the last year of his PhD, and officially joined us as a full-time employee after defending his dissertation on the role of fluvial discontinuities in shaping the geomorphology of New England. Andy’s research investigated how sediment transport and storage patterns are impacted by discontinuities to better characterize and understand the natural baseline conditions of river systems. He looks forward to build upon his experience now at Inter-Fluve, particularly with dam removals and reconnecting anadromous fish habitat.

A Massachusetts native and proud New Englander, Andy has lived, worked, and studied all over the region, including stints as a camp counselor in New Hampshire and Maine and as a whitewater rafting guide in Vermont and Western Mass. In his free time, Andy is an avid flyfisher, trail runner, and paddler.
