The Watershed Process and Sustainability Research Group (WPS or “WHOOPS!” for short) is out and about, wading through beautiful streams in central and coastal Maine. The team is making measurements to quantify water flow, water quality loads, stream channel stability, and headwater runoff patterns in Acadia, Wells, Damariscotta, Sebago, and other locations Downeast. The field measurements and desktop analyses that use the data are driven by several research projects focused on solutions to coastal bacteria pollution problems, development of better predictors of watershed runoff delivery patterns, and identification of stream impacts from land use alterations and climate change.
What do headwater streams in Maine look like and how do they change over time? Where do streams in coastal Maine watersheds begin? How do coastal watersheds respond to rainfall and what landscape characteristics influence pollutant delivery to tidal estuaries? Better numbers on streams and the flows they carry will help resource managers make decisions to protect Maine’s streams, rivers, lakes and estuaries. Here are shots from our recent travels!

Research Focus and History
My teaching and research focuses on watershed geomorphology with attention to processes that influence the morphology and stability of hillslopes and waterways, and that govern the flux of water, sediment and nutrients in the contemporary landscape. Topics of my past and present research include stream channel morphology and stability, surface flow patterns in headwater drainage basins, watershed sediment budgets, and modern watershed best management and rehabilitation practices. I am particularly interested in projects seeking to identify, quantify and explain changes to landscapes caused by human activities.
Much of my work is inspired by interests in advancing the measurement, description and prediction of environmental impacts across spatial scales ranging from single hillslopes to large watersheds and time scales spanning from a single rainfall event to millennia. I have extensive experience working in the Mid-Atlantic region of North America in collaboration with partners involved with the USEPA Chesapeake Bay Program. I have a joint appointment with the Senator George J. Mitchell Center for Sustainability Solutions and affiliation with the Maine Agricultural and Forest Experiment Station (MAFES).
Ongoing activities include participation in multiple interdisciplinary projects:
These projects involve faculty, post-doctoral researchers, graduate students, and undergraduate research assistants that comprise the School of Earth and Climate Science’s Watershed Process and Sustainability Research Group working in collaboration with multiple colleagues, government agencies, and project stakeholders in Maine and beyond.
