Scott Peckham is a Research Associate at the University of Colorado Boulder in Hydrology, Geomorphology, Modeling, and Cyberinfrastructure. His research interests include physically-based mathematical and numerical modeling, watershed-scale hydrologic systems, source-to-sink sediment transport, scaling analysis, differential geometry, component-based modeling, grid-based computational methods, efficient computer algorithms and fluvial landscape evolution models. Scott has authored numerous, open-source, earth surface process models including a spatially-distributed hydrologic model called TopoFlow and a fluvial landscape evolution model called Erode. He is also CEO and founder of Rivix, LLC which sells a software product for terrain and watershed analysis called RiverTools. Scott has been honored to pursue research as a NASA Global Change Student Fellow (1990-1993) and a National Research Council Research Associate (1995-1998).
