Dr. Pitlick’s research interests are in the areas of surface-water hydrology and fluvial geomorphology. His research focuses on processes of sediment transport and channel change in both natural and altered river systems. The principal goal of this research is to develop process-based models coupling hydrology, sediment transport, and geomorphology across a continuum of scales. Additional research being done in collaboration with fisheries biologists and aquatic ecologists seeks a more detailed understanding of interactions between geomorphology and ecosystem processes, including food-web dynamics and nutrient cy-
