About Dr. Alan Kasprak

I joined Fort Lewis College in the fall of 2020, and am an assistant professor in the Department of Geosciences. My research focuses understanding physical and biological processes in river systems using geospatial techniques. I am currently using GIS and remote sensing data to examine the impacts of large dams on the geomorphology, sediment transport, and land cover of the Colorado River corridor through the Canyonlands and Grand Canyon regions of the Southwestern U.S. I also conduct research into the role of in-channel wood in driving changes in stream morphology and fish habitat in rivers of the Greater Yellowstone Ecosystem. In addition to these field-based projects, I’ve conducted laboratory and numerical modeling studies of river response to altered sediment and water supply.

Prior to joining FLC, I completed a Master’s degree in Earth Sciences at Dartmouth College, a Ph.D. in Watershed Sciences at Utah State University, and held an appointment as a Mendenhall Postdoctoral Fellow with the U.S. Geological Survey’s Grand Canyon Monitoring and Research Center in Flagstaff, Arizona.
